Abstract:
Numerical procedures are well developed for simulating simple fluid flows and associated heat and mass transfer processes. Steady isothermal airflow in either a vertical laminar flow cleanroom or a tunnel cleanroom can be predicted accurately by using currently available simulation codes. The effects of items such as shields, process equipment, robot components, and bench design on the cleanroom airflow can be investigated by performing simulation experiments on a computer rather than physical experiments on a mockup. Design and operating parameters can be readily varied in the simulation to demonstrate their influence on the cleanroom performance. A review of existing airflow and particle transport simulation methods is presented and some recent applications to cleanroom airflow prediction are described. Advantages of computer simulation over experimental measurements and limitations are discussed, and future directions of cleanroom modeling are presented.

Abstract:
The aim of the work is to create new computer technologies for 3D modelling of heat and mass transfer processes in high-temperature physicochemically reacting environments that will allow to determine the aerodynamics of the flow and heat and mass transfer characteristics of technological processes occurring in the combustion chambers in existing coal-fired thermal power plants of the Republic of Kazakhstan. The novelty of the research lies in the use of the latest information technologies of 3D modelling, which will enable project participants to obtain new data on complex heat and mass transfer processes when burning pulverized coal in real combustion chambers operating in Kazakhstan’s Thermal Power Plants (TPP). A numerical simulation, including thermodynamic, kinetic and threedimensional computer simulation of heat and mass transfer processes when burning low-grade fuel, will allow finding optimal conditions for setting adequate physical, mathematical and chemical models of the technological process of combustion of burning high ash coals. The computer modelling methods proposed for the development are new and technically feasible, since coal-fired power plants all over the world use all types of coal. The developed technologies will allow replacing or eliminating the conduct of expensive and labour-consuming natural experiments on coal-fired power plants.

Abstract:
Cooling techniques for high density electrical components and electronic devices have been studied heavily in recent years. The advancements in the electrical/electronic industry have required methods of high heat flux removal. Many of the current electrical components and electronic devices produce a range of heat fluxes from 20 W/cm2 – 100 W/cm2. While parallel flow cooling systems have been used in the past, jet impingement is now more desirable for its potential to have a heat transfer coefficient 3-5 times greater than that of parallel flow at the same flow rate. Problems do arise when the jet impingement is confined and a cross flow develops that interacts with impinging jets downstream leading to a decrease in heat transfer coefficient. For long heated surfaces, such as an aircraft generator rotor, span wise fluid management is important in keeping the temperature distribution uniform along the length of the surface. A detailed simulation of the heat/mass transfer on a three-layer impingement/effusion cooling system has been conducted. The impingement jet fluid enters from the top layer into the bottom layer to impinge on the heated surface. The spent fluid is removed from the effusion holes and exits through the middle layer. Three different effusion configurations were used with effusion diameters ranging from 0.5 mm to 2 mm. Temperature uniformity, heat transfer coefficients, and pressure drops were compared for each effusion diameter arrangement, jet to target spacing (H/d), and rib configuration. A Shear Stress Transport (SST) turbulence fluid model was used within ANSYS CFX to simulate all design models. Three-layer configurations were also set in series for long, rectangular heated surfaces and compared against traditional cooling methods such as parallel internal flow and traditional jet impingement models. The results show that the three-layer design compared to a traditional impingement cooling scheme over an elongated heated surface can increase the average heat transfer coefficient by 75% and reduce the temperature difference on the surface by 75%. It was shown that for a three layer design under the same impingement geometry, the average heat transfer coefficient increases when H/d is small. The inclusion of ribs always provided better heat transfer and centralized the cooling areas. The heat transfer was increased by as much as 25% when ribs were used. The effusion hole arrangement showed minimal correlation to heat transfer other than a large array provides better results. The effusion holes' greatest impact was found in the pressure drop of the cooling model. The pressure losses were minimal when the effective area of effusion holes was large. This minimizes the losses due to contraction and expansion.

Abstract:
In this thesis. a three dimensional heat transfer model of heated airflow through the upper human respiratory tract consisting of nasal, oral, trachea, and the first two generations of bronchi is developed using computational fluid dynamics simulation software. Various studies have been carried out in the literature investigating the heat and mass transfer characteristics in the upper human respiratory tract, and the study focuses on assessing the injury taking place in the upper human respiratory tract and identifying acute tissue damage based on level of exposure. The model considered is for the simultaneous oronasal breathing during the inspiration phase with high volumetric flow rate of 90/liters minute and a surrounding air temperature of 100 degrees centigrade. The study of the heat and mass transfer, aerosol deposition and flow characteristics in the upper human respiratory tract using computational fluid mechanics simulation requires access to a two dimensional or three dimensional model for the human respiratory tract. Depicting an exact model is a complex task since it involves the prolonged use of imaging devices on the human body. Hence a three dimensional geometric representation of the human upper respiratory tract is developed consisting of nasal cavity, oral cavity, nasopharynx, pharynx, oropharynx, trachea and first two generations of the bronchi. The respiratory tract is modeled circular in cross-section and varying diameter for various portions as identified in this study. The dimensions are referenced from the literature herein. Based on the dimensions, a simplified model representing the human upper respiratory tract is generated.This model will be useful in studying the flow characteristics and could assist in treatment of injuries to the human respiratory tract as well as help optimize drug delivery mechanism and dosages. Also a methodology is proposed to measure the characteristic dimension of the human nasal and oral cavity at the inlet/outlet points which are classified as internal measurements.

Abstract:
The fundamental and quantitative study of heat and mass transfer processes in wood plays an important role for understanding many important production processes, such as wood drying and hot-pressing. It will help us improve the existing products and production techniques and develop new manufacturing technology. The most difficult aspect of the study is the complicated interactions of heat and mass transfer mechanisms. Extensive characterization of these physical processes using a strictly experimental approach is extremely difficult because of the excessively large number of variables that must be considered. However, mathematical modeling and numerical techniques serve as a powerful tool to help us understand the complicated physical processes. The goal of this research is to model the simultaneous heat and mass transfer in wood. The specific objectives of this research are: 1) develop a computer simulation program, implementing an existing one-dimensional mathematical drying model, using a finite difference approach, to numerically evaluate the mathematical model. 2) study sensitivity of the heat and mass transfer model to determine the effects of wood physical properties and environmental conditions on the drying processes.

Resumo: Nas últimas décadas, a intensificação de processos tem atraído a atenção da academia e da indústria. A Rotating Packed Bed (RPB) foi desenvolvida no contexto de intensificação de processos e tem sido amplamente usada em destilação, absorção, dessorção, dessulfuração, oxidação, cristalização, precipitação, polimerização e síntese de nanomateriais. Em uma coluna de destilação convencional, o fluxo de líquido está sob a influência da gravidade, como resultado, grandes colunas são requeridas para atingir altos níveis de separação. Para superar esta limitação, uma coluna de destilação com recheio rotativo (HIGEE High-gravity contactor) foi desenvolvida por Ramshaw e Mallison (1981) para realizar separações gás - líquido, a qual pode induzir forças centrífugas até 1000 vezes a força da gravidade. O incremento da força de contato entre as fases gera altos graus dos coeficientes volumétricos de transferência de massa e elevados limites de inundação (Ramshaw, 1983), permitindo uma redução de tamanho do equipamento comparado com o tamanho requerido para obter uma transferência de massa equivalente em colunas convencionais. Uma coluna HIGEE pode operar a altas vazões de gás ou líquido, devido à sua elevada capacidade de inundação. Além disso, este equipamento permite usar recheios com maior área superficial específica (2000-2500 m²/m³) e altas porosidades (0,90-0,95). Adicionalmente, utilizando colunas HIGEE podem ser obtidas grandes forças propulsoras do fluxo de líquido e diminuição nos tempos de residência devido à alta velocidade rotacional, o que permite que este equipamento opere com fluidos altamente viscosos, materiais sensíveis ao calor, e nanopartículas inorgânicas. A eficiência de transferência de massa aplicada a processos de destilação através de equipamentos com recheio rotativo tem sido estudada por poucos autores usando diferentes sistemas. Assim, o principal objetivo deste trabalho é simular uma coluna de destilação de alta eficiência (coluna HIGEE) no simulador comercial Aspen Plus V7.2, com o intuito de predizer o comportamento de separação do sistema etanol - água e compará-lo com o comportamento alcançado em uma coluna convencional. Para simular este equipamento no software comercial, foi preciso introduzir uma sub-rotina em Fortran que modificasse o modelo de transferência de massa de uma unidade existente. Estudou-se a eficiência de transferência de massa de uma RPB para diferentes condições de operação. Os resultados mostraram o potencial da coluna HIGEE como um processo intensificado que permite a redução considerável na altura e volume, comparado com uma coluna convencional com recheio, manifestando-se como uma alternativa promissória para o processo de destilação contínua
Abstract: In the last decades, the intensification of processes has attracted the attention of both academia and industry. A Rotating Packed Bed (RPB) was developed in the context of process intensification and it has been widely used in distillation, absorption, desorption, desulfurization, oxidation, crystallization, precipitation, polymerization, and nanomaterials synthesis. In a conventional distillation column, the liquid flows under the influence of the gravity. As a result, large columns are commonly required to achieve high levels of separation. To overcome this limitation, a rotating packed bed distillation column (HIGEE High-gravity contactor) was developed by Ramshaw and Mallinson (1981) for gas-liquid separations, which can induce centrifugal forces over 1000 times that of the earth's gravity. Increasing the driving force of contact between the phases allows greater degrees of volumetric coefficient of mass transfer and high flooding limits (Ramshaw, 1983) allowing a reduction of the size of the equipment in comparison with the size needed to obtain an equivalent mass transfer in a conventional column. A HIGEE column could be operated at a higher gas or liquid flow rate, due to very high flooding capacity. Moreover, it has been showed that this equipment allows the use of packings with a larger specific area (2000-2500 m²/m³) and higher void fraction (0.90- 0.95). In addition, larger driving force of liquid flow and reduced liquid residence time can be obtained in a HIGEE column due to the high rotational speed, which enables to operate equipment with very viscous fluids, heat sensitive materials, and inorganic nanoparticles. The mass transfer efficiency of a rotating packed bed contactor applied to distillation has been studied by few authors using different systems. Therefore, the main objective of this work is to simulate a distillation column of high efficiency (HIGEE Column) in the commercial simulator Aspen Plus V7.2, in order to predict the separation behaviour of the ethanol-water system and to compare this with conventional ones. In order to simulate this equipment in the commercial software, it was introduced a subroutine Fortran to account for the modification on the mass-transfer model of an existing unit. Mass transfer efficiency of RPB under different operating conditions was investigated. The results showed the potential of HIGEE column as an intensified process allowing a considerable reduction in height and volume in comparison with a conventional packed column, showing a promissory alternative for continuous distillation process

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:
Photocatalysis is a green technology that has been widely used in wastewater treatment. In this work, mass transfer processes in corrugated photocatalytic reactors were characterized both experimentally and through computer simulations. For the experimental work, various drum rotational speeds, reactor liquid volumes and number of corrugations were studied to elucidate their effects on mass transfer phenomena. The mass transfer rate was found to increase with increasing rotational speed. Liquid volumes in the reactor significantly affect the mass transfer rate when 20% of the surface area of the drum was immersed. A higher mass transfer rate was found using the drum with 28 corrugations, which had the lowest mass transfer coefficient when compared to the drums with 13 and 16 corrugations. In the computer simulations, velocity and concentration fields within the corrugated reactors were modelled to explore the characteristics of mass transfer processes. The mass transfer coefficients predicted by the simulations were lower than those measured experimentally due to mass transfer limitations occurring between the corrugation volume and bulk solution in the simulations. Based on mass transfer characteristics, it was determined that the drum with 28 corrugations was the most efficient photocatalytic reactor, and had the lowest mass transfer coefficient among those studied.

Full text
Abstract:
Over the past century the study of gas exchange rates between the atmosphere and the ocean has received increased attention because of concern about the fate of greenhouse gases such as CO2 released into the atmosphere. Of interest is the oceanic uptake of CO2 in shallow water coastal regions as biological productivity in these regions is on average about three times larger than in the open ocean. It is well-known that in the absence of breaking surface waves, the water side turbulence controls gas transfer of sparingly soluble gases such as CO2 from the air to the water. The dependence of gas transfer on wind-driven shear turbulence and convection turbulence generated by surface cooling has been investigated previously by others. However, the effect of Langmuir turbulence generated by wave-current interaction has not been investigated before. More specifically, Langmuir turbulence is generated by the interaction of the wind-driven shear current with the Stokes drift velocity induced by surface gravity waves. In this dissertation, large-eddy simulations (LES) of wind-driven shallow water flows with Langmuir turbulence have been conducted and scalar transport and surface scalar transfer dynamics analyzed. The scalar represents the concentration of a dissolved gas such as CO2 in the water. In flows with Langmuir turbulence, the largest scales of the turbulence consist of full-depth Langmuir circulation (LC), parallel downwind-elongated, counter-rotating vortices acting as a secondary structure to the mean flow. LES guided by the full-depth LC field measurements of Gargett & Wells (2007) shows that Langmuir turbulence plays a major role in determining scalar transport throughout the entire water column and scalar transfer at the surface. Langmuir turbulence affects scalar transport and its surface transfer through 1. the full-depth homogenizing action of the large scale LC and 2. the near-surface vertical turbulence intensity induced by the Stokes drift velocity shear. Two key parameters controlling the extent of these two mechanisms are the dominant wavelength (λ) of the surface waves generating the turbulence and the turbulent Langmuir number, Lat , which is inversely proportional to wave forcing relative to wind forcing. Furthermore, LES representative of the field measurements of Gargett et al. (2004) shows that Langmuir turbulence increases transfer velocity (a measure of mass transfer efficiency across the air-water interface) dramatically with respect to shear-dominated turbulence. Finally, direct resolution of the surface mass transfer boundary layer allows for the LES to serve as a testing ground for bulk parameterizations of transfer velocity. Several wellestablished parameterizations are tested and a new parameterization based on Stokes drift velocity shear is proposed leading to encouraging results.

Abstract:
Afin de prédire l’évolution de la composition chimique du laitier dans différents procédés sidérurgiques, un modèle CFD a été développé. Les coefficients de transfert de masse sont estimés à partir des modèles basés sur les paramètres physico-chimiques et hydrodynamiques, comme par exemple la diffusivité des espèces chimiques et la divergence de l’interface. Ces modèles ont été développé pour la prédiction du transfert gaz-liquide où le les nombres de Schmidt (Sc=ν⁄D) sont relativement faible (Sc≈200). Par contre, les procédés industriels ont un nombre de Sc considérablement plus importante, de l’ordre de 103 à 104. Pour évaluer la pertinence de ces modèles, l’hydrodynamique au voisinage d’une interface liquide-liquide a été étudiée. Un modèle CFD et des mesures par l’anémométrie laser (LDA) ont été utilisés pour calculer et valider les champs de vitesse d’une maquette à eau d’une lingotière de coulée continue (CC).Le modèle de transfert de masse d’une lingotière de coulée continu industriel nous a montré que les coefficients de transfert de masse ne sont pas distribués de manière homogène, et les propriétés physiques du laitier ne doivent pas y être non plus. Cette distribution non-homogène a été confirmée par des essais physiques. Les écoulements calculés numériquement ont été utilisé pour prédire les coefficients de transfert de masse entre les deux phases liquide. Ces paramètres seront utilisés comme donnée d’entré pour un modèle de thermodynamique afin de prédire l’évolution de la composition chimique du laitier
In order to characterize the mass transfer coefficients (MTC) of different species across liquid steel/slag interface, a multiphase Computational Fluid Dynamic (CFD) model was developed. MTC’s are estimated from models based on physicochemical and hydrodynamic parameters, such as mass diffusivity, interface shear and divergence strength. These models were developed for gas-liquid interactions with relative low Schmidt (Sc=ν⁄D) numbers (Sc≈200). However, the industrial processes involve mass transfer of chemical species with Sc number ranging from 103 to 104. To evaluate the applicability of these existing models, the fluid flow in the vicinity of a liquid/liquid interface is investigated. Computational Fluid Dynamic (CFD) and Laser Doppler Anemometry (LDA) were used to calculate and measure the velocity field on a continuous casting (CC) water model configuration. The work provides new insights and original measures to understand the fluid flow near liquid-liquid interfaces.The mass transfer model of an industrial continuous casting mold showed that the mass transfer coefficients are not homogeneously distributed, and slag properties should follow this trend. This non-homogeneity was confirmed by physical experiments performed with a water model of a CC configuration and its CFD representation. The calculated flow was used to predict the MTC and the interface area between phases, since the interface is constantly moving. These parameters will be the input of thermodynamic models to predict slag composition and viscosity. This methodology is currently under validation, and it will also be applied to improve steel plant performance in the desulphurization process

Abstract:
Flow, heat and mass transfer in a paint curing oven are studied numerically with a view to improving the energy efficiency of the oven and to control pollution. Painted products traverse the paint curing oven at a constant rate and in a fixed trajectory, and are heated by hot air jets which control the part temperature to ensure paint curing. Steady simulations are performed to compute the air flow and temperature fields. Computed air temperatures match experimentally measured values to an accuracy of 19% (temperatures calculated relative to the room temperature). Assuming thermal equilibrium between the painted part and the local gas flow, positiondependent smoke release rates due to paint curing are computed from the part temperature using experimentally measured cure rates. Smoke is modeled as a gas-phase species in a dilute mixture with air and its concentration and distribution in the oven are computed. The thermal behavior of the oven is captured in a parameter called the thermal performance index. The exhaust air mass flux is shown to have large impact on this index. Smoke loss to the outside environment is computed to quantify the degree of pollution. The impact of air seals on the thermal performance index and smoke release to the environment are quantified. Finally the effect of the thermal mass of the parts is considered and the convective and radiative effects are studied.

Abstract:
Analyzing trajectories of particles in monolith filters is important for predicting the capture efficiency and improving the design of this class of filters. Modeling and simulations of the particle trajectories are carried out to evaluate the probability of capture by the filter’s front surface and filter channel’s inner wall. Due to Brownian motion and electrostatic attraction, the particles exhibit a random walk and their trajectories deviate from the streamlines of the fluid flow. Particle trajectories are computed by the integration of Newton’s second law, where the electrostatic force, the Brownian motion force resulting from random collisions of the particle with air molecules, and the drag force from the surrounding fluid are all taken into account. A computer simulation for computing the particle trajectories and evaluating the probability of particle capture by the filter was developed. For this model, both flow field and electric field must be provided. The electric charge was assumed to be uniformly distributed along the edge of the channels of the filter and calculated numerically. The flow field is difficult to obtain due to the complex geometry of the model. The commercial CFD package ANSYS CFX [1] is used to compute the flow field. The resulting velocity flow field is then used to evaluate the drag force on the particles. We assume a one-way coupling between the fluid flow and the particle motion. Although there can be over one million uniformly distributed channels per square centimeter in the monolith filter, for simulation purposes, a single unit cell which models only one channel is used. The single unit model effectively describes the behavior of particles outside and inside the channels of monolith filter. The effects of different forces and different particle sizes were analyzed to investigate which factors affect the capture efficiency.

Abstract:
An interface tracking method for predicting bubble dissolution process is proposed. A non-diffusive scheme for advecting species concentrations is adopted to accurately compute the volume change due to mass transfer. The applicability of the proposed method is examined through several benchmark tests, i.e. mass transfer from a static bubble and that from free rising bubbles. Predicted species concentration distributions and mass transfer coefficients agree well with theoretical and empirical models. Dissolution of single carbon dioxide bubbles in a vertical pipe filled with water is also simulated. The bubbles consist only of carbon dioxide, and nitrogen and oxygen are initially dissolved in water. The volume change due to dissolution of carbon dioxide from the bubbles and evaporation of nitrogen and oxygen from water are well predicted.

Abstract:
Understanding heat/mass transfer mechanisms in turbulent flow is essential for solving many engineering problems. From the view point of heat/mass transfer control, surface roughness is popular for enhancing heat/mass transfer in turbulent pipe flow, relevant to heat exchangers, mixers, and nuclear reactors to name a few. Such a surface roughness is often modeled with a rib. In the current investigation, the flow and concentration fields from the LES data base were analyzed in detail. The profiles of mean velocity components, mean concentration, root-mean-squares (rms) of concentration fluctuations are presented at the selected streamwise locations downstream of a rib. In comparison with the straight-pipe case at the same Re and Sc, the effects of the ribs are clearly identified, leading to overall enhancement of turbulent mass transfer. The budget of concentration variance was computed and presented in the form of contours. Our LES results shed light on a complete understanding of the mass-transfer mechanisms in turbulent ribbed-pipe flow which has numerous applications in engineering.
