Abstract:
Concentrating solar technology plays a role, albeit a niche role compared to commercial solar systems (photovoltaics and thermal collectors). Within the context of sustainable development and within the green transition phase, it could be a respectable player. The main purpose of this study is to create and validate a model that approximates the temperature trend of a receiver installed in a CSP (concentrated solar plant). A method to approximate optical and thermal performance is discussed. The paraboloid installed in the Energy Center (Turin, Italy) was taken as a reference, creating a model that could simulate real operating conditions. The Monte Carlo (MC) method for ray tracing was adopted developing two models. The first model sets the maximum reflectivity of the paraboloid and neglects the loss of “limb darkening,” while the second one sets a reflectivity of 80%. Once the incident flux was obtained, the optical performance was analytically calculated and compared to the value provided by the manufacturer. The thermal performance was also studied, reproducing the dimensions of the receiver consisting of a sintered alumina tube placed at a focal distance from the paraboloid. Two configurations were analyzed: one neglecting the losses due to radiation and natural convection, the other one including the losses due to radiation and considering the atmospheric wind condition. Finally, the model was validated by comparing the obtained temperatures with those measured by thermocouples placed on the receiver. Analyzing two random days in the year 2020, an average error of 7% and 2% was obtained.

Abstract:
The paper investigates using a secondary solar concentrator to augment the solar energy density focused by a primary concentrator (a paraboloid dish). The secondary concentrator protects the focal point from cooling by convection from wind, and also would harness all the solar rays reflected by the primary concentrator, resulting in reduced losses due to aberration and other errors in finding the focal point. The intended application is the utilization of solar energy for nonferrous material ablation that could potentially replace or assist industrial lasers

Abstract— The solar energy is the most important type of energy. The parabolic dish solar collector (PDSC) is the best type among other solar collectors because it is always tracking the sun movement. The exergy and the energy performances of a PDS were analyzed experimentally and numerically. The effect of different coil geometries and different mass flow rates of heat transfer fluid (HTF) were investigated. The PDS has parabolic dish and receiver with diameter (1.5) m and (0.2) m respectively. Concentration ratio is 56.25. The parabolic polar dish was supported by a tracking system with two axes. The types of the copper absorber were used which are: (spiral –helical) coil (SHC) and spiral-conical coil (SCC). The results showed that the useful energy and thermal efficiency are varying with solar radiation variation. The useful energy varying between (480-765) W for (SHC), the thermal efficiency varying between (35.2-39.8) % for (SHC). Exergy efficiency varying between (6.9 –8.6) %. It was shown that the higher values of useful energy for (spiral – helical) absorber was 0.1L/min flow rate. REFERENCES 1. T. Taumoefolau , K.

Abstract:
Parabolic dish solar collectors gain higher solar to thermal conversion efficiency due to their maximum concentration ratio. The present research focuses by integrating the parabolic dish solar collector to the steam cycle producing power and rate of process heating. Pressurized water, therminol VP1, and supercritical carbon dioxide are the examined working fluids in the parabolic dish solar collector. The aim of the current research is to observe the optimal operating conditions for each heat transfer fluid by varying inlet temperature and flow rate of the working fluid in the parabolic dish solar collector, and combination of these parameters is predicted to lead to the maximum energy and exergy efficiencies of the collector. The operating parameters are varied to investigate the overall system efficiencies, work output, and process heating rate. Findings of the study declare that water is an efficient heat transfer fluid at low temperature levels, whereas therminol VP1 is effective for a higher temperature range. The integrated system efficiencies are higher at maximum flow rates and low inlet temperatures. The efficiency map of solar collector is located at the end of study, and it shows that maximum exergy efficiency gains at inlet temperature of 750 K and it is observed to be 37.75%.

Abstract:
Solar energy is a free natural resource but its harvesting requires a high capital investment whichprohibits its maximum exploitation. A Parabolic Dish Solar Collector (PDSC) with a thermalstorage system was been constructed and developed to harness solar beam radiation. The thermalstorage system and PDSC were constructed using locally and less cost materials such asgalvanized metal sheet and steel rods curved to obey the equation of a parabola then weldedtogether with circular support rings which was then lined with stainless steel reflector pasted forthe construction of PDSC. The receiver was made of blackened aluminium material incorporatedwith coiled copper tube carrying water as the heat transfer fluid. A parabolic dish which acts of aheat collector is used to track and reflects solar radiation at a single point (focus) on a receiverabsorber. Heat transfer from the solar collector to the storage tank was done by usingthermosyphonic principle to circulate the water (heat transfer fluid) between storage tank andheating system (receiver). The evaluation of thermal storage and analyzing the efficiency oftracking and non-tracking parabolic dish solar collector was carried out during month of June,2020 for the composite climate of Sokoto. According to the finding, the efficiency of trackingPDSC with thermal storage system and non- tracking PDSC with thermal storage tank weredetermined and obtained to be 52.9% and 50% respectively.Keywords: thermal efficiency, parabolic dish collector, solar radiation, storage system andstainless steel reflector.

This paper demonstrates the designing parameters of a solar parabolic dish prototype for rustic areas with great solar irradiance rate availability, where have no access of electricity services or low-income people survives to buy a stove (electric or gas). The solar parabolic dish prototype intends a solution against these types of remedies and pursues solar light to work. The parabolic dish has a polished surface, where the solar radiations fall and collected at a single concentrated focal point. At this point the collected form of energy is used to derive different thermal applications like as; cooking & heating with single and dual axis schemes. This paper discusses the important stages of dual axis prototype; implementation, solar location strategy, the analysis in terms of theory, structural design & material. The dual axis prototype is implemented through the help of Arduino chipboard that is easily in maintenance, along with that this prototype is configured with anti-lock H-bridge (L298) module to overcome the control circuit complexity and AVR modules. Two rotational motors of 12V are installed on 4*4ft designed aluminum frame with a dual-axis tracking system.

Abstract:
According to the methods of focusing,the solar thermal generation can be classified to tower system,parabolic trough system and dish-stirling system. The parabolic solar thermal generation system is an important type of solar thermal utilization. Compared to tower and dish-stirling system,the parabolic trough system has many advantages such as the small concentration ratio,the simple process,the low material requirement and the simple tracking device because of many concentrator on-axis tracking. The parabolic trough system is the lowest cost, least close to commercialization,larger potential system optimization,and the most suitable to large operation in this three thermal generation systems [1,. The parabolic trough system is composed of concentrator and receiver,and the receiver is the key component that uses solar energy to heat working fluids in receiver. Therefore,the key problem is how to make the solar energy transfer to subsequent generation system efficiently and stably.

Abstract:
Abstract The solar parabolic dish water heater is highly efficient but has limited hours of work only when sunlight is perpendicular to its surface. Therefore, this work aims to continue the work of the solar parabolic dish in the daytime using a dual tracking system, depending on the geographic location of the system (longitude and latitude angles) and using the C # programming language. To verify the effect of the dual-axis solar tracking system, the current study considered two types of solar parabolic dishes, the first was fixed, and the second was a rotating dish (by the dual tracking system). It was observed that the water temperature at the outlet of the tracking type solar water heater is 22% higher than that for the fixed dish type; this means that the proposed system has improved the temperature of water in the heat exchanger. Therefore, the highest water temperature value of about 51.4ffiC was at the outlet of the heat exchanger for the tracking type at 1:00 pm, while the temperature recorded for the fixed type was about 46.1ffiC. The highest energy gained from the solar heating system was at 1:00 pm for both types, which was about 76.9 W from the tracking type and 54.7 W from the fixed type. It was also observed that in the fixed dish type, most energy losses occurred during the daytime, while for the tracer of the dish type, useful energy was gained during most of the sunny working hours depending on the solar radiation intensity.

Abstract:
Concentrated Solar Power (CSP) constitutes one suitable solution for exploiting solar resources for power generation. In this context, parabolic dish systems concentrate the solar radiation onto a point focusing receiver for small-scale power production. Given the modularity feature of such system, the scale-up is a feasible option; however, they offer a suitable solution for small scale off-grid electrification of rural areas. These systems are usually used with Stirling engines, nevertheless the coupling with micro-gas turbines presents a number of advantages, related to the reliability of the system and the lower level of maintenance required. The OMSoP project, funded by the European Union, aims at the demonstration of a parabolic dish coupled with an air-driven Brayton cycle. By looking at the integrated system, a key-role is played by the solar receiver, whose function is the absorption of the concentrated solar radiation and its transfer to the heat transfer fluid. Volumetric solar receivers constitute a novel and promising solution for such applications; the use of a porous matrix for the solar radiation absorption allows reaching higher temperature within a compact volume, while reducing the heat transfer losses between the fluid and the absorption medium. The aim of the present work is to deliver a set of optimal design specifications for a volumetric solar receiver for the OMSoP project. The work is based on a Multi-Objective Optimization algorithm, with the objective of the enhancement of the receiver thermal efficiency and of the reduction of the pressure drop. The optimization routine is coupled with a detailed analysis of the component, based on a Computational Fluid Dynamics model and a Mechanical Stress Analysis. The boundary conditions are given by the OMSoP project, in terms of dish specifications and power cycle, whilst the solar radiation boundary is modelled by means of a Ray Tracing routine. The outcome of the analysis is the assessment of the impact on the receiver performance of some key design parameters, namely the porous material properties and the receiver geometrical dimensions. From the results, it is observed a general low pressure drop related to the nominal air mass flow, with several points respecting the materials limitations. One design point is chosen among the optimal points, which respects the OMSoP project requirements for the design objectives, i.e. a minimum value of efficiency of 70%, and pressure losses below 1%. The final receiver configuration performs with an efficiency value of 86%, with relative pressure drop of 0.5%, and it is based on a ceramic foam absorber made of silicon carbide, with porosity value of 0.94.  Moreover, the detailed analysis of one volumetric receiver configuration to be integrated in the OMSoP project shows promising results for experimental testing and for its actual integration in the system.

Abstract:
The present explored crude oil reservoirs are depleting at a much faster rate than estimated at the end of 20th century. The higher energy demand for transportation, industrialization and luxurious life are the main consequences behind this fast rate depletion. To fulfill the everlasting demand of energy, we need to look for some alternative source of energy. Biodiesel being renewable and less polluting fuel can replace the conventional diesel fuel. But the higher energy and cost of biodiesel production is not allowing the industries to look biodiesel as a conventional diesel alternative. Thus, solar energy is implemented as heating source for transesterification process to reduce the cost of biodiesel production from conventional methods. This study focuses on optimizing the yield parameters based on the Taguchi’s approach, a powerful tool to maximize biodiesel yield. A full factorial design of 27 experiments, the signal-to-noise (S/N) ratio and analysis of variance (ANOVA) are employed to investigate the influence of yield parameters at different levels. The main objective of the study is to determine the effects of molar ratio, reaction time and catalyst concentration on the production of biodiesel from linseed oil. Different yield parameters have different influence on the production of biodiesel. The different levels for yield parameters recommended were 6:1, 7.5:1 and 9:1 for molar ratio; 90 min., 105 min. and 120 min. for reaction time; and 0.5 wt%, 0.75 wt% and 1.0 wt% for catalyst (KOH) concentration, respectively. The samples are processed under different level of parameters and percentage yield for each sample is measured. The result showed that the higher the molar ratio better the yield. The optimum yield parameters were 9:1 molar ratio, 105 min. reaction time and 0.5 wt% catalyst concentrations, which produced optimum yield of 82.48%. While the maximum yield of 82.82% is attained for molar ratio 9:1, reaction time 120 min. and catalyst concentration 0.75 wt%. According to the ANOVA analysis, molar ratio is the dominating factor with 63.01% contribution.

Abstract:
The control of steam temperature in direct steam generation plants is challenging due to the complex physical process involved in turning water into steam, and the variable nature of solar radiation. This thesis explores the control of steam temperature at the outlet of a mono-tube cavity receiver powered by a 500m2 dish concentrator, using state feedback control. The dish concentrator, receiver and ancillary equipment constitute the SG4 once-through steam generation system at the Australian National University in Canberra, Australia. The control of temperature in the receiver employs a linear full state feedback control strategy. The controller manipulates the feed-water mass flow entering the receiver, to maintain constant steam temperature at the receiver outlet under variations in solar radiation, inlet flow conditions and ambient temperature. To implement the temperature controller, this thesis develops a dynamic model of the steam generation process in the receiver. The mono-tube cavity receiver consists of a single path of steel tubing coiled to form a cylindrical cavity with a frustum opening. The cavity side of the tube intercepts concentrated radiation from the dish concentrator and heats up. Water passes through the inside of the tube and absorbs heat, turning into superheated steam before leaving the receiver. The dynamic model of the receiver is a switched movingboundary description of the heat exchange process taking place in the absorber tube, including the transition between single and two-phase flow that water undergoes as it turns into superheated steam. The advantage of this modelling approach is that it provides a state-space representation of the receiver that is suitable for the development of state feedback controllers. Computer simulations in this thesis validate the receiver model, as they show good agreement with experimental measurements of the SG4 steam generation system. The practical implementation of the receiver temperature controller in this thesis requires a state observer to estimate the state of the mono-tube cavity receiver during operation. This thesis proposes a modified Extended Kalman Filtering scheme to compute the state of the receiver, built around the switched moving-boundary receiver model. The filtering scheme is implemented in computer simulations and demonstrated experimentally in the SG4 steam generation system as part of this thesis. The linear full state feedback temperature controller proposed in this thesis generates a feed-water mass flow command to control the temperature at the receiver outlet. The mass flow command is generated from three separate regulation mechanisms: a set of full state feedback gains, an integrator and a feedforward law. The feedback and integrator mechanisms are designed from a linear approximation of the receiver model, and the feedforward law corresponds to a steady state energy balix x ance in the receiver. The temperature controller is implemented in simulations and experimentally on the SG4 steam generation system. This thesis presents the first experimental results of the SG4 system running successfully with automatic steam temperature control.

Abstract:
Design processes and analytical modeling are presented showing creation of a low-cost concentrating photovoltaic-thermoelectric (PV/TE) hybrid power system for research and laboratory teaching built using a small upcycled satellite dish. Today, concentrated solar hybrid PV/TE systems are drawing significant research attention and funding investment. However, the literature lacks examples of how this cutting-edge energy technology can be made accessible at low cost for STEAEM education at universities, vocational institutions, and high schools. By applying Energy Engineering Laboratory Module (EELM™) design principles and pedagogy, a process is presented to make this technology easily accessible at low cost. The concentrating solar hybrid PV/TE system presented here is divided into four subsystems: 1) a concentrator, 2) a PV/TE generator, 3) data acquisition, and 4) a cooling system. The key engineering decisions governing the design for each sub-system are described. In addition, a thermodynamic analysis is presented to predict the on-sun steady-state temperature profile of the PV/TE generator at the focus of the concentrator and to determine how much electrical power it will produce. The concentrator used is a salvaged miniature satellite dish, which is coated with mirrored tape to reflect sunlight upon a focal point. Scavenged at no cost, the satellite dish is a sectioned paraboloid of rotation offset from the vertex and the axis of symmetry. However, which paraboloid section the dish represents is unknown. A technique is presented to find the focal point and to use this information to correctly position a shadow-casting gnomon to ensure proper on-sun alignment. A method to experimentally confirm the focal location and size the PV is also provided. A key research question for solar concentrating hybrid PV/TE power systems at this size scale is whether it is better to actively cool the TE cold side via forced convection or simply allow cooling via natural convection. The thermodynamic heat balance analysis presented to address this question finds that while forced convection does better cool the PV module, increasing its efficiency and power output, the parasitic energy expenditure of the cooling fan far exceeds the additional power produced. It is therefore more beneficial to rely on natural convection on the TE cold side to maximize power production of the overall PV/TE module. Two experimental apparatuses were built consisting of a PV module backed by TE generators and instrumented with thermocouples to determine the internal temperature gradient while multi-meters read steady-state PV and TE power output. A halogen lamp placed at various distances from this array approximates concentrated sunlight, which is measured via pyranometer. These experiments validate conclusions drawn from the theoretical model.

Abstract:
Parabolic dish concentrators have shown significant promise of generating competitive electric energy for grid and off-grid applications. The efficiency of a dish-electric system is strongly affected by the quality of the concentrator optics. Most parabolic systems consist of a number of facets mounted to a support structure in an approximate parabolic arrangement, where the individual facets have spherical or parabolic optical shapes. The individual facets must be accurately aligned because improper alignment can compromise performance or create hot spots that can reduce receiver life. A number of techniques have been used over the years to align concentrator facets. In the Advanced Dish Development System (ADDS) project, a color look-back alignment approach that accurately aligns facets (mirror panels) and in addition indicates quantitative information about the focal length was developed. Key factors influencing the alignment, some of which had very large effects on the quality of the alignment, were also identified. The influence of some of the key factors was characterized with a flux mapping system on the second-generation ADDS concentrator. Some of these factors also affect other alignment approaches. The approach was also successfully applied to two other concentrators with differing facet arrangements. Finally, we have extended the method to a 2-f approach that eliminates the need for a distant line-of-sight to the dish and permits alignment at near vertical dish attitudes. In this paper, we outline the color look-back alignment approach, discuss the key alignment factors and their effect on flux distribution, and discuss extensions to non-gore dishes. A companion paper discusses the 2-f color alignment approach in detail.

Abstract:
In this paper an experimental thermal analysis made to a conical receiver attached to a solar parabolloid dish concentrator is presented, the purpose of this study is to know if it fulfills the requirements as far as quality and amount of energy demanded by a generator of a solar thermal cooling system (Solar-Branched-GAX Cycle). The analyzed system consists of a conical receiver of 19 cm of diameter by 20 cm of height, which was mounted to a focal length of 80 cm in a communications conventional antenna of 190 cm diameter, prepared with a reflecting coat. The concentrator was mounted in a multipurpose proving stand of solar collectors, with a solar tracking system in two axes. The analysis was carried out by evaluating experimentally three cases, which consisted of: A) receiver smooth, B) Receiver smooth with glass cover and C) Receiver with fins in the inner tail cone. According to the obtained results it can be concluded that the system of parabolloid disc concentrator using a conical receiver with fins is a very interesting option to be used as a generator of a solar thermal refrigeration system, since steam for a volumetric flow of 0.480 l/min can be generated.

Abstract:
Due to the moist and humid climate weather in Thailand, it is longer than six months of rainy season each year. Thailand is thus one of the many other countries in the world that has medium insolation, the average per year at 500 W/m2. Furthermore, the whole country sit on a very soft-land flat plateau. Since the Siam Solar Dish prototype was setup and tested at Naraesuan University in Pitsanulok Province and at AREF in Bangkok, Thailand, it became apparent that the design of her support structure together with her concrete foundation also represents a complicate part of these research activities. In Thailand, a parabolic dish structure is under development for various applications in between the 300–600 °C temperature range in solar fields up to several kilowatts range. The detail in this paper is one part of the solar thermal dish Stirling for a 10 kW power plant with lead acid battery storage in Thailand, namely the “Siam Solar Dish I” research project. This paper is the only one part of the main of this research project about Siam Solar Dish System effort in Thailand. That will explain the dish structure’s design structure and its foundation, which is suitable for Thailand’s soft land environmental nature. Parabolic dish systems normally feature different structural types in terms of their performance and durability. In order to implement a successful parabolic dish system, it thus became obvious by this nature that the design of each dish structure is quite important and vital to conduct a particular design calculation to match and suit with its individual installation location. This particular part of the research project activities is to design the requirement lightweight support structure, along with the parabolic dish structural design work, and the concrete foundation suitable to the soft land country like Thailand. The design effort continue to consider additional relevance topics, like the economized cost, the structural durability, and easy to control, together with the low maintenance cost to trade off with the required light weight structure.

Abstract:
A parabolic dish concentrator for electricity generation is currently under development at the Instituto de Investigaciones Ele´ctricas (IIE) of Mexico, a government-owned research organization. The concentrator is 7.5 meters in diameter with focal length to diameter ratio of 0.6. The reflective surface consists of 12 facets made of fiberglass with a reflecting surface made of aluminum sheet with a solar reflectance of 86%. The system will use a 9 kW Stirling engine to produce electricity from concentrated solar radiation. The paper describes preliminary and final design characteristics of the parabolic dish structure. Criteria for facet design, material selection, and structural configuration are reviewed. A detail explanation of tooling, substrate preparation and facets assembly is also presented. The key features and requirements of the tracking system, Stirling motor and control unit are also described.

Abstract:
Abstract The DISS (DIrect Solar Steam) project is a complete R+TD program aimed at developing a new generation of solar thermal power plants with direct steam generation (DSG) in the absorber tubes of parabolic trough collectors. During the first phase of the project (1996–1998), a life-size test facility was implemented at the Plataforma Solar de Almería (PSA) to investigate under real solar conditions the basic DSG processes and evaluate the open technical questions concerning this new technology. This paper updates DISS project status and explains O&M-related experience (e.g. main problems faced and solutions applied) with the PSA DISS test facility since January 1999.
