This is a state-of-the-art review of various treatments of earthquake loaded liquid filled shells by the methods of earthquake engineering, fluid dynamics, structural and soil dynamics, as well as the theory of stability and computational mechanics. Different types of tanks and different possibilities of tank failure will be discussed. We will emphasize cylindrical above-ground liquid storage tanks with a vertical axis. But many of the treatments are also valid for other tank configurations. For the calculation of the dynamically activated pressure due to an earthquake a fluid-structure-soil interaction problem must be solved. The review will describe the methods, proposed by different authors, to solve this interaction problem. To study the dynamic behavior of liquid storage tanks, one must distinguish between anchored and unanchored tanks. In the case of an anchored tank, the tank bottom edge is fixed to the foundation. If the tank is unanchored, partial lifting of the tank’s bottom may occur, and a strongly nonlinear problem has to be solved. We will compare the various analytical and numerical models applicable to this problem, in combination with experimental data. An essential aim of this review is to give a summary of methods applicable as tools for an earthquake resistant design, which can be used by an engineer engaged in the construction of liquid storage tanks.

A container to store water in a huge amount of capacity can simply be called as the water tank. During the earthquakes, all these liquid storage tanks get collapsed or damaged heavily. 40 to 65 years is the feasible lifetime of an ESR in general. Shortage of drinking water, utilizing water, uncontrolled fires, etc are some unexpected events caused due to any damage or collapse of the tanks. Water tank parameters include various designs of tanks and different way of construction, materials, linings etc. Different materials are used for the construction and development of water tanks such as: - plastic, concrete, steel, fiberglass, etc. Therefore, to avoid all those unwanted events in the future various studies have been carried out regarding different types, shapes of water tanks. In this research, Elevated Service Reservoir (E.S.R) is being compared of shape Rectangular & Circular water tanks of capacity 5lakh litres and a total height of 18m with 3m, 4.5m staging height in Earthquake Zone V by Equivalent static analysis using STAAD.PRO software and referring GSDMA guidelines for the design of a tank and IS 1893 PART2-2014 code. By studying all the observations and results, it shows that Circular water tank is more preferable and economical for use.

Abstract Tanks for the storage of oil and gas play a special role in the oil and gas industry. During the construction and design of such structures in difficult geological conditions, increased attention is paid to their safe operation. The combined manifestation of seismic impacts and the presence of permafrost can pose an increased danger. The article presents an analysis of the various components of an oil and gas storage system. A comparative analysis of the seismic resistance of storage tanks was carried out, taking into account the presence of a thawed permafrost base in the base. It is shown that during thawing, the permafrost base can greatly affect the seismic resistance of the structure.

Abstract An analytical study aiming the design of cylindrical liquid storage tanks resting on deformable foundations is developed in this work. The soil under the tanks is modeled as an elastic linear medium. The cylindrical wall is considered rigidly connected to the plate foundation. Here, concrete tanks are emphasized, although the study can be extended to other construction materials. For the analysis of the design forces acting on the tanks, efficient and simplified approximate expressions are derived based on rigorous analytical theories for thin shells and circular plate on elastic foundations. To verify the proposed approximate expressions and investigate the influence of the foundation deformability on displacements and design forces, parametric analyses of concrete tanks with different soil stiffness values are presented. The results illustrate the strong influence of the foundation stiffness on the tank design quantities and a very good performance of the simplified expressions.

It is shown that the most expedient method for ensuring the design geometry of the tank with a minimum stress of 1.4507 of the material structure, is the bottom sheets preset for welding at a reverse angle of 12 degrees.The proposed method improves the tank reliability for storing aggressive products, its trouble-free and technical safety during the operation. The need is shown for studying the replacement of imported steel by Russian steel to manufacture tanks from alternative nonmetallic materials.

Full textAbstract:
A comparative study of performance of various isolation systems for liquid storage tanks is investigated under real earthquake ground motions. The various base isolation systems considered are the laminated rubber bearings (with and without lead core) and sliding isolation systems (with and without restoring force). The isolated liquid storage tank is idealized with three-degrees-of-freedom associated with convective, impulsive and rigid mass under uni-directional earthquake excitation. Since the force-deformation behaviour of the isolation systems is non-linear, as a result, the equations of motion are solved numerically by step-by-step method. In order to measure the effectiveness of the isolation systems, the seismic response of the isolated liquid storage tanks is compared with the corresponding response of non-isolated tanks. Further, the effectiveness of the isolation is also explored for wide range of practical liquid storage tanks considering the influence of tank aspect ratio. It is observed that the isolation systems are quite effective in attenuating the earthquake acceleration transmitted to the tank, which reduces the design seismic forces significantly. Further, it is also found that the sliding type isolation systems are more effective in controlling the response of liquid storage tanks in comparison to the elastomeric bearings. Among the various sliding systems, the resilient-friction base isolator is found to be most effective for seismic isolation of the tanks.

Abstract In many parts of the world, drinking water storage takes place in near-house or in-house tanks. This can impact drinking water quality considerably. International and numerous national standards and guidelines addressing the construction, installation and operation of domestic drinking water storage tanks are reviewed on their consideration of water quality aspects and the minimisation of health risks associated with drinking water storage. Several national and international standards and guidelines are reviewed in terms of drinking water quality requirements. Factors that have an impact on water quality in relation to the use of domestic drinking water storage tanks are summarised comprehensively. The impact of the domestic storage of drinking water on water quality, the points and locations of use, their positioning, the materials they are made of, their design and operation, as well as aspects of how they are operated and maintained is outlined and discussed in detail. Finally, the incorporation of aspects regarding water quality in drinking water storage tanks in standards and guidelines is presented and assessed. To make the use of domestic drinking water storage tanks safer and more efficient, recommendations for modifications, improvements and extensions of respective standards are made.

Introduction. Vertical steel tanks are extensively used in oil fields to hold crude oil and other liquids. Their construction requires continuous surveying control. However, measurement procedures, data processing, and deviations and documentation correction are not universal and cannot be applied for tanks with a capacity of less than 3000 m3. Moreover, the process of correcting the detected bottom irregularities is poorly substantiated and intuitive. Research objective is to improve the as-built survey accuracy and reliability of the low-capacity steel tank bottom, substantiate the minimum height of its irregularities, increase the objectivity and productivity of measurement processing, develop an unambiguous method for time-predictable correction of bottom irregularities, and substantiate the optimal contents of its relief’s as-built scheme. Methods of research. Geometric leveling for the bottom profile survey failed to provide adequate accuracy and was therefore replaced by the method of trigonometric leveling. A method has been developed for determining the deviations of the existent tank bottom profile from the design position by means of algebraic actions with surfaces of a topographic order. The accuracy of determining the smallest height of bottom irregularities has been estimated under the tacheometric survey. A method has been proposed for controlling the correction of tank bottom irregularities based on evaluation calculations of bottom deformations by the finite element method. Research results. All the development results are exemplified by a specific production example. It was found that for a full completion of work, two iterations of tank bottom irregularities correction are enough. Methods of optimal design for the facility’s as-built schemes are presented. Conclusions. A simple, accurate, low-cost, productive, and time-predictable method of mine surveying, mathematical processing and correction of deviations in the tank bottom profile has been developed. This technique reduces the construction period and increases the operating time of the facility.

Increasing energy consumption in residential and public buildings requires development of new technologies for thermal energy production and storage. One of possibilities for the second listed need is the use of phase change materials (PCMs). This work is focused on solutions in this area and consists of two parts. First one is focused on different designs of thermal energy storage (TES) tanks based on the phase change materials. The second part is the analysis of tests results for TES tank containing shelf and tube heat exchanger and filled with phase change material. Thermal energy storage tank is analyzed in order to use it in domestic heating and hot utility water installations. The aim of this research was to check the applicability of phase change material for mentioned purpose. Results show that using phase change materials for thermal energy storage can increase amount of stored heat. The use of properly selected PCM and heat exchanger enables the process of thermal energy storing and releasing to become more efficient.

Full textAbstract:
Steam accumulation is one of the most effective ways of thermal energy storage (TES) for the solar thermal energy (STE) industry. However, the steam accumulator concept is penalized by a bad relationship between the volume and the energy stored; moreover, its discharge process shows a decline in pressure, failing to reach nominal conditions in the turbine. From the economic point of view, between 60% and 70% of the cost of a steam accumulator TES is that of the pressure vessel tanks (defined as US$/kWhth). Since the current trend is based on increasing hours of storage in order to improve dispatchability levels in solar plants, the possibility of cost reduction is directly related to the cost of the material of pressure vessels, which is a market price. Therefore, in the present paper, a new design for steam accumulation is presented, focusing on innovative materials developed specifically for this purpose: two special concretes that compose the accumulation tank wall. Study of dosages, selection of materials and, finally, scale up on-field tests for their proper integration, fabrication and construction in prototype are the pillars of this new steam accumulation tank. Establishing clear and precise requirements and instructions for successful tank construction is necessary due to the highly sensitive and variable nature of those new concrete formulations.

Oil tanks must meet the requirements of low evaporation losses, as well as durability and longevity. Oil tanks are made of steel and non-metal structures of different materials. Steel oil tanks are small (up to 2000 Pa), high (up to 70,000 Pa) and atmospheric pressure due to the additional pressure in the gas phases. Due to their design, steel oil tanks are vertical cylindrical, horizontal cylindrical, drip-shaped and trench-type. Vertical cylindrical oil tanks are the most common and are mainly conical, spherical, pantone, floating lid. Pantone and floating oil tanks - used to reduce evaporation losses during oil storage. The pantone installed in the oil tank with a capacity of 20,000 m3 consists of a steel floor made of a 4 mm thick layer of steel and a ring with two lids welded along its perimeter at a distance of 2.8 m from each other. These ribs provide rigidity to the pontoon during movement, as well as a reserve swimming position when the middle part of the panto sinks. The annular ribs are connected at a certain distance from each other (up to 1/48 of the circumference) by radial ribs. The annular and radial ribs are welded to the floor of the pantone with a complete seam. Keywords: cover construction, oil storage terminal, oil tanks volume, determination of the coating structure.

In this paper, the relation between the steel cylindrical tank geometry and the governing critical damage mode of the tank shell is numerically determined for all practical ranges of liquid storage tanks (aspect ratio H/D = 0.2 to 2). In addition, the interaction between the seismic intensity, soil type, acceptable seismic risk and tank geometry along with the extra material demanded by the seismic loads is examined based on the provisions of major codes. The importance of seismic factors on the economics of the design of a liquid tank in zones with high seismic activity is comprehensively discussed. In this regard, an empirical relation to estimate the steel volume required for specific seismic conditions and tank geometries is proposed based on the results of analysis.

The construction of large oil depots has become increasingly important, and oil storage safety also becomes a hot topic. It can be seen from multiple major safety accidents that have occurred in recent years that lightning is considered being one of the main causes of oil tank fires. Through in-depth research on safety issues, we are trying to find a scientific and economical safety management model for oil depots. Most of the objects stored in the oil depots are flammable liquids, and the oil gases which are produced by oil products can easily cause an explosion. A little carelessness may cause casualties and huge economic losses. The main purpose of this research is to design a lightning protection system for fixed roof oil tanks on the ground. By providing a complete design of lightning protection, to show how to ensure the safety level of the oil tank and oil depots, then the authors briefly describe other latest technologies for lightning protection which could be used in the future improvement.

Silos and tanks are both industrial storage containers, so it may be imagined that they can be treated in a common manner for structural design. However, the statistical base of reliability theory shows that tanks are exceptionally invariant in their loading, while loads in silos are possibly the most unpredictable of all structural engineering loads. This article sets out the arguments why the statistical scatter of loads on tanks should be seen as very small indeed. It then treats the problems of loads on silos at length, showing that a wide range of different factors dramatically influence the safety of the structure, leading to a situation in which the use of a single value for the partial factor on stored solid loads could be either very uneconomic or else unsafe. It shows that the known key parameters that define the form of the structure, the aspect ratio, the properties of the stored solids, the manner of filling and discharge, and the frequency of usage of the silo should all play a strong role in determining appropriate values of design partial factors. The recommended values for the partial factors should therefore be evaluated using rules placed in EN 1991-4.

Nowadays, the floating production storage and offload system (FPSO) is one of the most common platform types for offshore oil production. The traditional arrangement of the stiffened panels creates obstacles for automated cleaning and inspections by remote devices. This paper summarizes the results of an initial study for the design and construction of FPSO hulls with SPS in order to overcome this problem. The main goal is to have the walls and bottom of the cargo tanks free of stiffeners. This research is conducted by first designing the hull with a conventional structural arrangement using steel according to the ABS rules as a benchmark. Following that, the equivalent hull structure with sandwich plates is designed in accordance with the guidelines for SPS construction from DNV rules. Finally, this paper provides the results of a finite element analysis to compare the stresses and ultimate strengths of both types of structures. Briefly, the main results are that the SPS design provides a reduction of 2.8% of the total weight and a better overall structural performance by an increase of 26% for the ultimate strength of the hull.

In recent years, more emphasis has been put on source control measures in order to reduce the peak runoff from urban areas during wet weather conditions. This involves the construction of upstream storage and infiltration facilities and rainwater tanks for reuse in households and the revaluation of ditches. Because of the long emptying times of source control facilities, a long antecedent period of rainfall influences the design. In addition, these facilities most often have an outflow which is not linearly varying with the storage. Because of the high variability of the rainfall, the required storage volumes can therefore only be assessed well if continuous simulations with long rainfall series are performed. Based on long-term simulations design rules have been set-up for source control measures in Flanders.

The ensuring of the minimum metal consumption of the structure, the reducing the labour-intensiveness of its manufacture and assembly in the construction of steel prismatic bunkers, designed for storage and unloading of free-flowing materials, are entirely determined by the quality of the design structure. The disadvantage of bunker designs is the connection of the side panels at right angles, which causes the unevenness of the stress-strain state and, as a consequence, the occurrence of emergencies. Some studies suggest that one of the main specific causes of bunker breakdowns and damages is related to incorrect determination of structural loads. A number of authors propose the use of multilayer complex design with the utilization of corrugatedsteel sheets, which directed to address the issue of reducing metal consumption. Today there is still no complex approach to solving the problem of ensuring the reliable operation of the structure owing to searching the best structural forms, technologies for its manufacture and assembly.In this connection, the purpose of this work is to develop the design of the prismatic bunker, which allows to ensure operational reliability, production manufacturability and minimal attended costs associated with the construction of the struc-ture on the building site. By means of modeling the stress state in the structures of bunker tanks, the optimal constructive design options were determined, particularly, dimensional parameters and layout of vertical and stiffeningplates.To ensure the operational reliability of bunker tanks, a solution has been developed that provides for the use of stiffening plates in the design of bunker funnel, which ensure the combined work of its sheet part with the stiffening frame. Use of the block principle of construction of bunker tanks allows to increase a degree of factorial readiness of dispatch elements and to reduce labourintensiveness on assembly sites.

Full textAbstract:
Base isolation of liquid storage tanks has proven to be an efficient seismic protection measure, leading to a drastic reduction of a superstructure’s distress. However, many such tanks are located near seismic tectonic faults, which generate strong pulse-like ground motions that can impose excessive displacement demands on the isolators. For this reason, viscous dampers are incorporated into the isolation system to avoid overconservative isolators design. To optimize the seismic performance of hybrid isolation systems consisting of single friction pendulum bearings and linear viscous dampers, two novel multi-objective optimization approaches are proposed in the current study. Furthermore, suitable constraint functions and design variables are selected, considering the most critical parameters of the hybrid isolation system. The multi-objective genetic algorithm optimizer is used for the solution of both problems. The results are presented in the typical form of Pareto and certain optimal design solutions are carefully chosen and compared in terms of isolators fragility curves and tank accelerations. The main aim is to optimize the critical design parameters by achieving a reasonable balance among contradicting objectives. The tank industry can substantially benefit from this study, as a more cost-efficient design of hybrid base-isolation can be attained for large-scale tanks.

In this paper it is aimed to present the detailed design procedure of the first solar power system in Jeddah. A prototype of solar power tower system was built at King Abdulaziz University in Jeddah, Saudi Arabia where direct irradiation is very high. Heliostats were used to track the incident sun rays and focus the energy flow towards a solar receiver. The system consists of 10 heliostats directing incident solar rays to a tower of height about 7 meters. Two motors were used to control the heliostat rotational and elevation movements. A solar receiver made of alloy steel is installed at the top of the tower to collect solar energy reflected from the heliostats. A molten salt fluid consists of sodium and potassium nitrates (60/40) re-circulated in the receiver transfers the collected heat in the receiver to a storage tank. A cylindrical vessel with height of 1 m and diameter of 1.5 m was adopted for each of the cold and hot tanks. The design thermal power was 13 kW. The percentage error in the thermal power obtained is about 5.3%.

Full textAbstract:
Solar hot water tanks (SHWT) based on a latent heat storage system are gaining momentum for their integration into solar heater water collectors. They can efficiently store daytime solar thermal energy and shift on-peak period loads to off-peak periods. However, their performance is generally limited by the tank configuration, the design of the thermal storage system, and the selection of the appropriate phase change material (PCM). This work presents a numerical investigation of three SHWT-PCM storage designs. A mathematical model was developed to predict the effectiveness of the geometric design and operating conditions in the SHWT-PCM system. Moreover, a sensitivity analysis was performed on the PCM type and PCM thermo-physical properties. The obtained numerical results demonstrated that the energy efficiency of the SHWT-PCM system was significantly impacted by the PCM thermo-physical properties (melting temperature, thermal conductivity, and enthalpy). In addition, it was found that using encapsulated PCM tubes with an external PCM jacket in the SHWT can result in a thermal efficiency of 70%.

Introduction. The most widely used for the storage of oil and petroleum products at industrial enterprises both in Russia and abroad, were vertical steel cylindrical tanks). However, despite the significant world experience in the design, construction and operation of vertical steel cylindrical tanks, from time to time their failures (destruction) occur, leading to negative consequences. Interacting with normative earthen landslides or enclosing walls, the resulting powerful hydrodynamic flow of liquid flows through them, spilling over a large area, involving in the incident nearby tanks, buildings, structures, pipelines, which leads to the cascading development of the accident, significant material damage, often to injuries and loss of life. Thus, a more detailed consideration of the effectiveness of existing ways to minimize the negative consequences of tanks destruction, as well as problematic issues of some promising methods on the topic under consideration, seems relevant. Goals and objectives. Identify the most effective ways to minimize the negative consequences of possible destruction of vertical steel cylindrical tanks. Analyze the consequences of characteristic accidents of vertical steel cylindrical tanks at production facilities. To propose a classification of methods on the basis of preventing or localizing the breakthrough wave formed during the destruction of vertical steel cylindrical tanks. To consider the problematic issues of promising ways to localize flammable liquid. Methods. In the process of developing a number of ways to minimize the negative consequences of accidents on vertical steel cylindrical tanks, methods of similarity theory and laboratory modeling, physical experiment, observation, comparison, finding empirical dependencies based on mathematical processing of experimental data, description, generalization were used. Results and their discussion. It has been established that the most effective way is to eliminate the dangerous factor (breakthrough wave) through the use of underground or horizontal tanks. Effective ways to localize the flow of liquid include the arrangement of an enclosing wall with a wave reflective visor or a protective wall additional to the normative fence. A promising method includes the construction of tanks of the "glass in a glass" type. Conclusion. The effectiveness of the considered methods should be taken into account, first of all, by the owners of hazardous production facilities, specialists of design organizations and supervisory authorities to find optimal solutions for the safe operation of tanks, including, if necessary, their placement in settlements, near water areas and federal highways. Keywords: tank, destruction, breakthrough wave, earthen collapse, enclosing wall, enclosing wall with a wave reflective visor, additional protective wall, "glass in a glass" tank.

Full textAbstract:
In the current study, a high temperature thermal storage system with a hybrid of phase change material and graphite as the storage materials is designed and evaluated as to its applicability for use as a utility-scale Carnot battery. The design includes an externally heated liquid sodium tank, which is used as the heat transfer fluid. This is used to charge and discharge the storage system consisting of a graphite storage medium sandwiched by two phase change materials. Finally, electrical generation is by way of a supercritical carbon dioxide Brayton cycle operated at 700 °C. Detailed modelling of these designs was conducted by way of a previously validated numerical model to predict performance metrics. Using the aforementioned designs, a preliminary cost estimate was undertaken to better determine applicability. From these results, it was found that while the graphite system was the most effective at storing energy, it was also the highest cost due to the high cost of graphite. In total, 18 storage tanks containing nearly 17,400 tons of storage material were required to store the 1200 MWht required to run the sCO2 power block for 10 h. Under the study conditions, the cost of a PCM-based Carnot battery was estimated to be $476/kWhe, comparable to other storage technologies. Furthermore, it was found that if the cost of the graphite and/or steel could be reduced, the cost of the system could be reduced to $321/kWhe.

Full textAbstract:
Austenitic stainless steels are the major material of construction for the fast breeder reactors in view of their adequate high temperature mechanical properties, compatibility with liquid sodium coolant, good weldability, availability of design data and above all the fairly vast and satisfactory experience in the use of these steels for high temperature service. All the Nuclear Steam Supply System (NSSS) components of FBR are thin walled structure and require manufacture to very close tolerances under nuclear clean conditions. As a result of high temperature operation and thin wall construction, the acceptance criteria are stringent as compared to ASME Section III. The material of construction is Austenitic stainless steel 316 LN and 304 LN with controlled Chemistry and calls for additional tests and requirements as compared to ASTM standards. Prototype Fast Breeder Reactor (PFBR) is sodium cooled, pool type, 500 MWe reactor which is at advanced stage of construction at Kalpakkam, Tamilnadu, India. In PFBR, the normal heat transport is mainly through two secondary loops and in their absence; the decay heat removal is through four passive and independent safety grade decay heat removal loops (SGDHR). The secondary sodium circuit and the SGHDR circuit consist of sodium tanks for various applications such as storage, transfer, pressure mitigation and to take care of volumetric expansion. The sodium tanks are thin walled cylindrical vertical vessels with predominantly torispherical dished heads at the top and bottom. These tanks are provided with pull-out nozzles which were successfully made by cold forming. Surface thermocouples and heaters, wire type leak detectors are provided on these tanks. These tanks are insulated with bonded mineral wool and with aluminum cladding. All the butt welds in pressure parts were subjected to 100% Radiographic examination. These tanks were subjected to hydrotest, pneumatic test and helium leak test under vacuum. The principal material of construction being stainless steel for the sodium tanks shall be handled with care following best engineering practices coupled with stringent QA requirements to avoid stress corrosion cracking in the highly brackish environment. Intergranular stress corrosion cracking and hot cracking are additional factors to be addressed for the welding of stainless steel components. Pickling and passivation, Testing with chemistry controlled demineralised water are salient steps in manufacturing. Corrosion protection and preservation during fabrication, erection and post erection is a mandatory stipulation in the QA programme. Enhanced reliability of welded components can be achieved mainly through quality control and quality assurance procedures in addition to design and metallurgy. The diverse and redundant inspections in terms of both operator and technique are required for components where zero failure is desired & claimed. This paper highlights the step by step quality management methodologies adopted during the manufacturing of high temperature thin walled austenitic stainless steel sodium tanks of PFBR.

Thermal energy and its need for humans will always be a serious issue. We come into contact with heat anywhere. From warming yourself by the fireplace, to taking a nice bath in warm water. Sufficient heat needs to be provided for all areas of society. Using thermal energy storage makes sense for heat sources that cannot deliver the required amount of heat in a short period of time. To ensure that there is always enough heat, the efficiency of heat-handling equipment needs to be improved. This requires a sufficient number of experts to further develop the domain of heat accumulation. Students’ education in this domain through laboratory exercises is the proper step. Students acquire theoretical knowledge and practical skills. At the same time, they test the efficiency of heat storage and look for innovation in this domain. It will be achieved specifically, by designing a heat storage tank teaching model in various designs from the perspective of material construction, heat bearing medium and by changing other parameters of the storage tank or measuring environment. They also compare computer simulations to see what effect the direction of flow of the heat transfer medium has on the functionality of the heat storage device. By subsequently measuring and processing the collected data, students can determine the effectiveness of individual designs of this heat storage device learning model. They can then use the acquired knowledge and practical skills in practice.

Hydrogen has been considered as a feasible energy carry for fuel cell vehicles, which offers a clean and efficient alternative for transportation. In the currently developed hydrogen compression cycle system, hydrogen is compressed through a compressor and stored in the tank as high pressure. The hydrogen is filled from high pressure station into hydrogen storage system in fuel cell vehicles. In the study, theoretical and simulation are performed by presenting a mathematical model for the temperature rise during filling process in the hydrogen storage tank at the pressure of 50 MPa compressed hydrogen system. For a high-pressure tank (HPT) that can store hydrogen at a hydrogen filling station, the temperature rise of hydrogen with the pressure change during the filling process, the amount of hydrogen filling in the tank, and the convective heat transfer coefficient in the tank were calculated. The calculated temperature was compared with numerical and theoretical methods. Appropriate theoretical formulas were presented through mathematical modeling for changes that occur when high-pressure storage tanks were filled, and hydrogen properties were analyzed using the REFPROP program. 3D modeling was performed for the high-pressure storage tank, and the analysis was conducted under adiabatic conditions. When the pressure was increased to 50 MPa in the initial vacuum state, and when the residual pressure was 18 MPa, it was 25, 50, 75,and 100 MPa, and hydrogen inside the storage tank of the temperature rise and the amount of hydrogen filling were investigated. The results of this study will be useful for the design and construction of compressed hydrogen tank for hydrogen charging system.

In order to evaluate the feasibility and performance of liquid lead-bismuth eutectic as the heat transfer fluid for thermocline heat storage tanks in solar power systems, we conducted an effect evaluation of filling medium parameters on the integrated operating and mechanical performances of a thermocline tank using liquid lead-bismuth eutectic using the computational fluid dynamics simulation method. Four parameters were evaluated: the porosity, thermal conductivity, specific heat capacity, and equivalent diameter of the filling medium. The results show that the liquid lead-bismuth eutectic tank operated stably. The total charging and total discharging durations were 5.7 h and 5.3 h, respectively, and the discharging efficiency was 91.94%. The effect evaluation results reveal that the discharging thermocline thickness of the liquid heavy metal tank can be decreased by increasing the specific heat capacity of the filling particles, or by decreasing the porosity, thermal conductivity, and equivalent diameter of the filling medium. The total discharging quantity of the tank increased from 2.19 × 1010 J to 3.34 × 1010 J when the specific heat capacity of the filling particles increased from 610.0 J/(kg∙K) to 1010.0 J/(kg∙K), while the other three filling medium parameters had no obvious effect on the total discharging quantity of the tank. The mechanical performance of the tank wall could be improved by decreasing any one of the four evaluated parameters of the filling medium. The results of this paper may serve as a reference for the design of actual liquid heavy metal heat storage tanks in solar power plants.

A significant part of the oil consumed in the world is transported from production and processing sites to consumers via tankers and pipelines. According to experts' forecasts, the demand for oil and petroleum products in the coming years will be significantly higher than in 2020. In Russia, the oil transportation market is developing in several directions. The main directions are investing in pipeline transport and improving the design of tanks for storing oil and petroleum products. The article considers the contribution of the great Russian engineer V.G. Shukhov to the solution of the problem of oil transportation and storage and in general to the development of the oil industry. In the article "Oil Pipelines" (1884) and in the book "Pipelines and their application in the oil industry" (1894), V.G. Shukhov gave precise mathematical formulae for describing the processes of oil and fuel oil flowing through pipelines, creating a classical theory of oil pipelines. He is the author of the projects of the first Russian main pipelines: Baku-Batumi with a length of 883 km (1907) and Grozny-Tuapse with a length of 618 km (1928). Shukhov V.G. designed and then supervised the construction of oil pipelines of the companies "Branobel", "G.M. Lianozova and sons" and the world's first heated fuel oil pipeline. Working in the oil fields in Baku, Shukhov V.G. developed the basics of lifting and pumping oil products, proposed a method of lifting oil using compressed air — airlift, developed a calculation method and technology for the construction of cylindrical steel tanks for oil storage facilities.

With the continuous upgrading of hardware in the terminal equipment, how to provide high-performance computing for low-tech threshold users has become a current research hotspot. In the era of green high-performance computing, the heterogeneous computing system can provide good versatility, performance, and efficiency and has broad development prospects. This article provides an in-depth analysis and research on the construction and application of improved models using the artistic design pattern of heterogeneous tasks and parallel computing. Based on the hardware resources in the existing desktop system, this article optimizes the original heterogeneous parallel technology from the aspects of task division and data transmission to reduce the complexity of data allocation and processing for users. Based on the analysis and study of the multicore CPU and GPU architectures in the desktop system, as well as the original CPU-GPU heterogeneous parallel technology, this article optimizes the solution of heterogeneous parallel computing, designs a heterogeneous parallel computing architecture, and deploys a heterogeneous parallel computing architecture. The nodes of the desktop system constitute the parallel computing system. In terms of task allocation, the computing system divides tasks according to the parallelism of tasks. According to the computing resources and bandwidth conditions of each heterogeneous node, starting from the parallel execution time, the task scheduling algorithm is optimized, and the load balancing scheduling scheme is designed to achieve the optimal allocation of resources. In terms of storage resources, the computing system adopts distributed storage as a whole. The CPU-GPU heterogeneous parallel in the desktop system adopts virtual unified storage. Global distributed storage and local shared storage are used to balance overall performance and programming complexity. This article introduces the design and implementation of JTangSync, a distributed heterogeneous data synchronization system. The system adopts a distributed architecture, and each node is organized by a data source module, a data transmission module, a processor module, etc. The data source module is responsible for extracting data, the data transmission module is mainly responsible for efficient data transmission, and the processor module is responsible for data processing. More importantly, each module is designed as a replaceable plug-in, which is convenient for secondary expansion. Each node relies on ZooKeeper to form a cluster, which realizes distributed functions such as centralized management of distributed resources, failover, and resumed transmission. Compared with the mainstream scheduling algorithms HEFT, CPOP, PEFT, and HSIP on heterogeneous systems participating in the experimental evaluation, the scheduling length ratio of DONF series algorithms is reduced by 36.3%–67.5% and the parallelism is increased by 17%–125% in terms of efficiency. Compared with the existing database synchronization system, the JTangSync system has built-in multiple heterogeneous database data sources and supports the synchronization of complex heterogeneous databases. The system supports users to develop and customize their own data sources and data processing programs, to promote secondary development. By adopting the custom compressed data exchange format and network optimization methods such as packet merging, caching, and adaptive compression algorithm, the system has high performance.

The goal of sustainable construction is to improve the energy efficiency of a building, which today is a challenge for software developers, builders, owners within the constraints of time, cost, provision and resources. Building functional, sustainable, safe, comfortable and easy-to-use buildings will increase consumer demand. The problem of implementing sustainable construction lies in the division of responsibilities and tasks from the relevant specialists. This article explores the role of Building Information Modeling (BIM) in reducing fragmentation among professionals at every stage of construction. The possibility of using a virtual storage of information using BIM is analyzed, which provides easy access to data and their exchange in real time. Thus, BIM provides a professional platform for working in an integrated environment at any stage of the building construction process. When analyzing Russian and foreign sourcesthe prerequisites are being created for the future research required to generate improvements towards sustainable construction.

The leakage of hazardous materials due to the defect in storage tank foundations is likely to cause tremendous fire disasters in the industry cluster area. Thus, adequate design and construction of the tank foundation is required for preventing tank leakage. In this study, four types of typical tank foundations were classified and modeled for 3D FEM analysis to perform stability evaluation on tank foundations. Furthermore, numerical analysis indicated that stress concentration just below the tank shells is 40 times that at the tank center. The settlement influence zone is about the tank radius and tank diameter in the horizontal and vertical directions, respectively. Thus, the appropriate guidelines for the design and construction of tank foundations were suggested via a comparison assessment of the numerical analysis results on the stress distribution and displacement of the tank foundations.
