Abstract:
The purposeof this study is to analyze methods of mathematical modeling for calculating the stage of primary sublimation, as the most important stage in lyophilization technology. Presented are mathematical formulas, equations for the calculation of heat and mass transfer processes, during the removal of 90 % of all frozen ice. A model is considered that takes into account the contribution of all thermal effects, including the transient energy balance, taking into account the heat transfer through the side wall of the vial and radiation, even if they are present in a small amount. The mathematical model can be used to optimize the lyophilization cycle, and also as tools for technological monitoring (using sensors based on models). The model considered in the article is a one-dimensional nonstationary state model in which the correct comprehensive transient energy balance has been introduced to describe the heat transfer through the glass of the vial, and the results are estimated using experimental data. The equations used in the simulation describe the mass and energy balances in the dried layer, taking into account the rate of adsorption/desorption of water at the interface, mass and heat transfer at the sublimation interface, as well as the energy balance of heat transfer in the wall of vials, shelf and other factors affecting the process of sublimation. Conclusions are made on the presented mathematical models and the characteristic of the direction of the process of optimization of primary sublimation in lyophilization technology is given.

Resumo: Este projeto utilizou a tecnologia supercrítica no processo de extração, usando o dióxido de carbono como solvente. Esta tecnologia apresenta-se como uma alternativa para processos que usam solventes orgânicos tóxicos, além de respeitar os princípios da química verde, pautada nos conceitos de desenvolvimento sustentável. Com o objetivo de compreender melhor todos os mecanismos fenomenológicos envolvidos neste processo, bem como poder controlá-los visando à sua otimização, a modelagem matemática é uma opção bastante atrativa. As substâncias capsaicinoides, presente em grandes quantidades em várias espécies de pimenta, responsáveis pela sensação pungente e que, no entanto, possuem comprovadas ações benéficas ao organismo, foram definidas como substâncias alvo. Desta forma, para os estudos dos fenômenos de transferência de massa, três espécies de pimentas, Capsicum frutescens, Capsicum chinense, Capsicum boccatum, foram analisadas quanto aos seus teores de capsaicinoides. A espécie Capsicum frutescens apresentou o maior concentração destas substâncias e foi escolhida como a matéria-prima para etapas posteriores. Um planejamento experimental de extração supercrítica desta espécie de pimenta foi realizado variando a pressão e a temperatura. A partir destas extrações foi observado que a condição de extração de 15MPa e 313 K apresentou a melhor combinação entre rendimento e concentração de capsaicina. Cinéticas de extração realizadas nesta condição, porém variando a vazão de solvente, o diâmetro de partícula e o volume de extração, foram estudadas. Maiores taxas de extração foram obtidas nas maiores vazões e nos menores diâmetros de partícula e volume de leito de extração devido à maior importância do fenômeno convectivo. O modelo de partículas intactas e rompidas de Sovová (1994) foi usado para ajustar os dados experimentais das curvas e obter os parâmetros do modelo. Três tipos de modelagem foram realizadas: ajuste de cada curva individualmente; ajuste simultâneo gerando um conjunto de parâmetros para os pares das duplicatas; ajuste múltiplo que ajustou um valor único do parâmetro XK para cada conjunto de curvas com o mesmo diâmetro de partícula. Com os ajustes foi possível calcular o coeficiente convectivo de transferência de massa de cada condição e o respectivo valor do número de Sherwood experimental. Com os dados experimentais de cada condição foram calculados os números adimensionais de Reynolds e Schimdt. Com estes novos conjuntos de dados de números adimensionais foram realizadas novas modelagens matemáticas e, através destas, propostas novas correlações. Estas novas equações foram baseadas tanto na existência única da convecção forçada quanto na existência, mesmo que pouco significativa, da convecção natural. A eficácia destes novos modelos foi avaliada com a comparação dos coeficientes de transferência de massa convectivos calculados com aqueles ajustados das curvas experimentais, apresentando, em geral, boa similaridade. Por fim, uma extração em escala piloto realizada deu indícios, através dos resultados calculados das novas correlações, que a convecção natural nestas escalas não pode ser desprezada
Abstract: This workt used the supercritical technology in the process of extraction, using carbon dioxide as solvent. This technology is based on concepts of sustainable development and respects the principals of green chemistry. It appears as an alternative to processes that use toxic organic solvents. Mathematical modeling is an interesting tool to understand better all phenomenological mechanisms involved in this process and to be able to control and optimize them. Capsaicinoids, which are responsible for the pungent sensation caused by peppers, have well-known beneficial properties for human organism. These substances are present in large quantities in several pepper species. Capsaicinoids were chosen as target substances for the study of mass transfer phenomena. Capsaicinoid contents were analyzed for three pepper species: Capsicum frutescens, Capsicum chinense, Capsicum boccatum. The species Capsicum frutescens showed higher concentration of these substances and was chosen as raw material for further steps. An experimental design of supercritical extraction from this pepper species was carried out varying pressure and temperature. These extractions showed that the extraction condition of 15 MPa and 313 K gave the best combination of yield and capsaicin concentration. Therefore, extraction kinetics was studied under this condition, varying solvent flow rate, particle diameter and extraction bed volume. The highest extraction rates were obtained for high solvent flow rates, low particle diameters and low extraction bed volume. This can be explained by the greater importance of the convective phenomenon under these conditions. The Sovová¿s model (1994) for intact and broken particles was used to fit experimental data to curves and obtain model parameters. Three types of mathematical modeling were established: (1) fitting of each individual curve, (2) simultaneous fitting creating a set of parameters for pairs of duplicates, (3) multiple fitting that adjsuts a single value for the parameter XK for each set of curves with the same particle diameter. These fits allowed calculating the convective mass transfer coefficient for each condition and the respective values of the experimental Sherwood number. Experimental data was used to calculate dimensionless numbers of Reynolds and Schmidt for of each condition. Other mathematical modelings were performed using these new data sets of dimensionless numbers, which allowed proposing new correlations. These new equations were based on the existence of forced and free convection, even though the importance of the second phenomenon was considered small. The efficiency of these new models was assessed with a comparison of calculated convective mass transfer coefficients to those fitted from experimental curves. A good coherence was found between both. Finally, a pilot scale extraction was performed and the results obtained using the proposed correlations suggested that free convection cannot be neglected at such scales

Abstract:
Hollow fibre and spiral wound membrane (SWM) modules are the most common commercially available membrane modules. The latter dominate especially for RO, NF and UF and are the focus of this study. The main difficulty these types of modules face is concentration polarisation. In SWM modules, the spacer meshes that keep the membrane leaves apart also help reduce the effects of concentration polarisation. The spacer filaments act as flow obstructions, and thus encourage flow destabilisation and increase mass transfer enhancement. One of the detrimental aspects of the use of spacers is an increase of pressure losses in SWM modules. This study analyses the mechanisms that give rise to mass transfer enhancement in narrow spacer-filled channels, and investigates the relationship between flow destabilisation, energy losses and mass transfer. It shows that the regions of high mass transfer on the membrane surface correlate mainly with those regions where the fluid flow is towards the membrane. Based on the insights gained from this analysis, a series of multi-layer spacer designs are proposed and evaluated. In this thesis, a Computational Fluid Dynamics (CFD) model was used to simulate steady and unsteady flows with mass transfer in two- and three-dimensional narrow channels containing spacers. A solute with a Schmidt number of 600 dissolving from the wall and channel Reynolds numbers up to 1683 were considered. A fully-developed concentration profile boundary condition was utilised in order to reduce the computational costs of the simulations. Time averaging and Fourier analysis were performed to gain insight into the dynamics of the different flow regimes encountered, ranging from steady flow to vortex shedding behind the spacer filaments. The relationships between 3D flow effects, vortical flow, pressure drop and mass transfer enhancement were explored. Greater mass transfer enhancement was found for the 3D geometries modelled, when compared with 2D geometries, due to wall shear perpendicular to the bulk flow and streamwise vortices. Form drag was identified as the main component of energy loss for the flow conditions analysed. Implications for the design of improved spacer meshes, such as extra layers of spacer filaments to direct the bulk flow towards the membrane walls, and filament profiles to reduce form drag are discussed.

Abstract:
Heat actuated adsorption heat pumps offer the opportunity to improve overall energy efficiency in waste heat applications by eliminating shaft work requirements accompanying vapor compression cycles. The coefficient of performance (COP) in adsorption heat pumps is generally low. The objective of this thesis is to model the adsorption system to gain critical insight into how its performance can be improved. Because adsorption heat pumps are intermittent devices, which induce cooling by adsorbing refrigerant in a sorption bed heat/mass exchanger, transient models must be used to predict performance. In this thesis, such models are developed at the adsorbent particle level, heat/mass exchanger component level and system level. Adsorption heat pump modeling is a coupled heat and mass transfer problem. Intra-particle mass transfer resistance and sorption bed heat transfer resistance are shown to be significant, but for very fine particle sizes, inter-particle resistance may also be important. The diameter of the adsorbent particle in a packed bed is optimized to balance inter- and intra-particle resistances and improve sorption rate. In the literature, the linear driving force (LDF) approximation for intra-particle mass transfer is commonly used in place of the Fickian diffusion equation to reduce computation time; however, it is shown that the error in uptake prediction associated with the LDF depends on the working pair, half-cycle time, adsorbent particle radius, and operating temperatures at hand. Different methods for enhancing sorption bed heat/mass transfer have been proposed in the literature including the use of binders, adsorbent compacting, and complex extended surface geometries. To maintain high reliability, the simple, robust annular-finned-tube geometry with packed adsorbent is specified in this work. The effects of tube diameter, fin pitch and fin height on thermal conductance, metal/adsorbent mass ratio and COP are studied. As one might expect, many closely spaced fins, or high fin density, yields high thermal conductance; however, it is found that the increased inert metal mass associated with the high fin density diminishes COP. It is also found that thin adsorbent layers with low effective conduction resistance lead to high thermal conductance. As adsorbent layer thickness decreases, the relative importance of tube-side convective resistance rises, so mini-channel sized tubes are used. After selecting the proper tube geometry, an overall thermal conductance is calculated for use in a lumped-parameter sorption bed simulation. To evaluate the accuracy of the lumped-parameter approach, a distributed parameter sorption bed simulation is developed for comparison. Using the finite difference method, the distributed parameter model is used to track temperature and refrigerant distributions in the finned tube and adsorbent layer. The distributed-parameter tube model is shown to be in agreement with the lumped-parameter model, thus independently verifying the overall UA calculation and the lumped-parameter sorption bed model. After evaluating the accuracy of the lumped-parameter model, it is used to develop a system-level heat pump simulation. This simulation is used to investigate a non-recuperative two-bed heat pump containing activated carbon fiber-ethanol and silica gel-water working pairs. The two-bed configuration is investigated because it yields a desirable compromise between the number of components (heat exchangers, pumps, valves, etc.) and steady cooling rate. For non-recuperative two-bed adsorption heat pumps, the average COP prediction in the literature is 0.39 for experiments and 0.44 for models. It is important to improve the COP in mobile waste heat applications because without high COP, the available waste heat during startup or idle may be insufficient to deliver the desired cooling duty. In this thesis, a COP of 0.53 is predicted for the non-recuperative, silica gel-water chiller. If thermal energy recovery is incorporated into the cycle, a COP as high as 0.64 is predicted for a 90, 35 and 7.0°C source, ambient and average evaporator temperature, respectively. The improvement in COP over heat pumps appearing in the literature is attributed to the adsorbent particle size optimization and careful selection of sorption bed heat exchanger geometry.

Abstract:
Continental and submarine hydrothermal systems are commonly found around the world. Similar systems that sustain water or other fluids are also likely to exist in planetary bodies throughout the solar system. Also, terrestrial submarine systems have been suggested as the locations of the first life on Earth and may, therefore, provide indications of where to find life on other planetary bodies. The study of these systems is vital to the understanding of planetary heat transfer, chemical cycling, and biological processes; hence hydrothermal processes play a fundamental role in planetary evolution. In this thesis, three particular types of hydrothermal systems are investigated through the development of mathematical models: (1) terrestrial low-temperature diffuse flows at mid-oceanic ridges (MORs), (2) submarine near-axis convection on Earth, and (3) convection driven by magmatic intrusives on Mars. Model set-ups for all systems include a two-dimensional space with a vertical, hot wall, maintained at constant temperature, located adjacent to a water-saturated porous medium at a lower temperature. By assuming that convection occurs vigorously and within a thin layer next to the hot wall, boundary layer theory is applicable. The models provide steady-state, single-phase estimates of the total heat and mass transfer rates in each scenario over permeability ranges of 10-14 m2 to 10-10 m2 for the submarine systems and 10-14 m2 to 10-8 m2 for the Martian systems. Heat output results derived from the boundary layer model suggest that diffuse flow on MORs contributes 50% or less of heat output to the ridge system, which falls at the low end of observations. For the near-axis model, results found that heat transfer in the hydrothermal boundary layer was greater than the input from steady state generation of the oceanic crust by seafloor spreading. This suggests that the size of the mushy zone evolves with time. Heat output and fluid flux calculations for Martian systems show that fluid outflow adjacent to a single intrusion is too small to generate observed Martian surface features in a reasonable length of time.

CAPES
Na indústria do petróleo existe um grande interesse no entendimento dos fenômenos de formação de hidratos já que eles podem danificar a tubulação, colocar vidas em risco e diminuir a produção de óleo e gás pelo bloqueio da linha. Ou seja, conhecer os fenômenos associados à formação de hidratos reflete diretamente no custo operacional da indústria petrolífera. Diversos grupos de pesquisa já propuseram diferentes modelos para predizer o crescimento de hidratos na interface líquido-gás e na parede das tubulações de produção de petróleo em águas profundas. Entretanto, os modelos baseados unicamente na transferência de calor não foram adequados para explicar os dados experimentais pois os consumos de água e gás não eram considerados. Assim, esta dissertação tem como objetivo desenvolver um modelo, matemático e numérico, que permita prever o crescimento dos hidratos de metano e de dióxido de carbono na parede da tubulação por meio das equações de conservação de massa e energia de forma acoplada. Como nenhuma solução analítica é possível, foi utilizado o método numérico dos volumes finitos com o esquema totalmente implícito. A verificação da implementação computacional foi realizada utilizando um modelo de dissociação de hidratos existente na literatura. A partir dos resultados numéricos, foi avaliado como as condições termodinâmicas, a porosidade e a condutividade térmica do hidrato, o diâmetro da tubulação e a disponibilidade de gás influenciam na taxa de crescimento de hidrato. Como principais resultados, verificou-se que a porosidade e a disponibilidade de gás representaram grande importância no cálculo da taxa de crescimento da camada de hidrato.
The study of the clathrate-hydrate formation processes in pipelines is very important to the oil and gas industry because these structures can stop production and it represents a safety risk due to the pressure build-up in the pipelines. Several research groups have proposed different models to predict how a hydrate film grows. However, the models based only on heat transfer could not explain satisfactorily the experimental data because the water and gas consumption were disregarded. So, in order to predict the hydrate growth phenomenon in tube wall, the current work presents a mathematical and numerical model for the coupled mass and energy balance problem for CO2 and CH4 hydrates. As a result of the coupling equations, no analytical solution is possible. So, a computational algorithm has been proposed based on the finite volume method and fully implicit scheme. The verification of the code was conducted through a dissociation model which has been presented by the literature. Although, its validation was not possible since no experimental data is currently available. The hydrate growth rate was evaluated by studying the influence of the thermodynamic conditions, the hydrate porosity and thermal conductivity, the pipe diameter and the gas availability. As a result, it has been noticed that the hydrate porosity and the gas availability had great influence in the hydrate growth rate.

Abstract:
Two variants of the crystallizer are considered: in the first, the solution is supplied to the central crystal part, in the second, there is a peripheral solution supply along the crystallizer perimeter, what provides creating its swirling flow. The calculation models corresponded to the laminar and turbulent regimes of the solution flow during the mixed KCNSH crystal growth from a mixture of two water-salt solutions (cobalt KCSH and nickel KNSH salts).

Abstract:
This paper introduces a mathematical model which can be used to simulate the capillary pumping process of a micro heat engine. The micro heat engine has micron sized channels where the capillary pumping occurs. The classic Volume of Fluids (VOF) method is applied to obtain the velocity profiles of the fluids and to track the motions of the liquid-gas interfaces. The numerical results based this model have been compared with the experimental data and the initial retard of the pumping has been found and this phenomenon can be explained by the initial capillary pressure build-ups across the liquid-gas interfaces.

Abstract:
This paper describes a mathematical model developed to study the behavior of LPG tanks when subjected to jet fire. The model consists of a number of field and zone sub-models which are used to simulate the various physical phenomena taking place during the tank engulfment period. The comparisons between the model predicted results and the test data showed better agreement. The results showed that the jet fire partially impingement on tank wall led to higher wall temperatures and the time to failure was shorter than in engulfing pool fire. And the fire exposure started at the vapor wall is under more dangerous situation than the fire exposure at the bottom of the tank.

Abstract:
The article deals with the mental-existential relationship between ethnoculture, national identity and media culture as a necessary factor for their preservation, transformation, on the example of national original algorithms, matrix models, taking into account global tendencies and Ukrainian archetypal-specific features in Ukraine. the media actively serve the domestic oligarchs in their information-virtual and real wars among themselves and the same expansive alien humanitarian acts by curtailing ethno-cultural programs-projects on national radio, on television, in the press, or offering the recipient instead of a pop pointer, without even communicating to the audience the information stipulated in the media laws − information support-protection-development of ethno-culture national product in the domestic and foreign/diaspora mass media, the support of ethnoculture by NGOs and the state institutions themselves. In the context of the study of the cultural national socio-humanitarian space, the article diagnoses and predicts the model of creating and preserving in it the dynamic equilibrium of the ethno-cultural space, in which the nation must remember the struggle for access to information and its primary sources both as an individual and the state as a whole, culture the transfer of information, which in the process of globalization is becoming a paramount commodity, an egregore, and in the post-traumatic, interrupted-compensatory cultural-information space close rehabilitation mechanisms for national identity to become a real factor in strengthening the state − and vice versa in the context of adequate laws («Law about press and other mass media», Law «About printed media (press) in Ukraine», Law «About Information», «Law about Languages», etc.) and their actual effect in creating motivational mechanisms for preserving/protecting the Ukrainian language, as one of the main identifiers of national identity, information support for its expansion as labels cultural and geostrategic areas.
