Jiang, Wenbiao. "Simulation du bullage dans un photobioréacteur". Thesis, Université Paris-Saclay (ComUE), 2018. http://www.theses.fr/2018SACLC086/document.
The working principle of a typical photobioreactor is to inject gas bubbles into the culture medium, providing CO2 to the cells and also stirring the liquid. Subsequently, the cells convert inorganic carbon into organic carbon through photosynthesis under illumination. Therefore, physical phenomena, e.g. bubbly flow, mass transfer, radiative transfer, and biological phenomena, e.g. photosynthesis, cell growth and death, coexist in a photobioreactor. More importantly, all the basic phenomena are not completely independent to each other. For example, bubble volume and bubble shape can influence gas-liquid mass transfer according to Young-Laplace equation and Henry's law. Moreover, some recent research revealed that bubble behaviors also directly affect the biological process. In view of the important impact of bubble behaviors on productivity of a phototbioreactor, the bubbly flow was investigated in this thesis by both experimental and numerical methods.In the experimental study, we first manufactured a new photobioreactor in order to study the bubbles and other phenomena. Subsequently, the bubbles were captured by high speed camera by virtue of a shadowgraphy technique and bubble behaviors were obtained by processing and analyzing the images. From the experimental results, we found that both averaged bubble volume and bubbling frequency increased with gas flow rate. Furthermore, we also discovered that the distribution of bubble volume was almost monodisperse at low flow rate, and it became more and more polydisperse with increasing flow rate. Regarding bubble shape evolution, we used two shape factors, viz. aspect ration and circularity, to quantitatively study it. We found that both shape factors dropped rapidly during bubble rising (within the limit of the field of view of our video camera), which implied that bubbles were flattened in the course of rising. Nonetheless, bubbles became more vertically elongated at higher flow rate, partially due to the more frequent bubble coalescence at higher flow rate.In the numerical study, we adopted VOF method and OpenFOAM, an open source CFD library, as our numerical tool to represent bubbly flow. First of all, the robustness of OpenFOAM in simulating two-phase flow was validated by literature survey. Subsequently, 2D simulations were carried out for seeking the appropriate and not very time-consuming numerical parameters, i.e. maximum Courant number and mesh size. We found that mesh size should somehow be smaller than the nozzle diameter to have meaningful results. On the other hand, maximum Courant number had no particular importance in the simulations (as long as between 0 and 1). Furthermore, 3D simulations were in good agreement with the experiments in terms of bubble volume and bubble shape evolution. However, 3D simulations were not able to represent the polydispersity of bubble volume due to the limited computing power. In addition, several hydrodynamic characteristics were also explored by the proposed numerical tool, which gave reasonable results.To conclude, bubble behaviors were successfully captured by experimental methods and represented by numerical methods in this thesis, which will help us go further in understanding the complicated physical-biological phenomena of a photobioreactor

Malan, Leon. "Direct numerical simulation of free-surface and interfacial flow using the VOF method : cavitating bubble clouds and phase change". Thesis, Paris 6, 2017. http://www.theses.fr/2017PA066555/document.
Direct numerical simulation of two-phase ow is used extensively for engineering research and fundamental fluid physics studies [54, 81]. This study is based on the Volume-Of-Fluid (VOF) method, originally created by Hirt and Nicols [30]. This method has gained increased popularity, especially when geometric advection techniques are used coupled with a planar reconstruction of the interface [14, 89]. The focus of the first part of this work is to investigate the hydrodynamics of isothermal cavitation in large bubble clouds, which originated from a larger study of micro-spalling [61], conducted by the French CEA. A method to deal with volume-changing vapour cavities, or pores, was formulated and implemented in an existing code, PARIS . The ow is idealized by assuming an inviscid liquid, negligible thermal effects and vanishing vapour pressure. A novel investigation of bubble cloud interaction in an expanding liquid using direct or detailed numerical simulation is presented. The simulation results reveal a pore competition, which is characterised by the Weber number in the ow. In the second part of the study the governing equations are extended to describe incompressible ow with phase change [79]. The description of the work commences with the derivation of the governing equations. Following this, a novel, geometric based, VOF solution method is proposed. In this method a novel way of advecting the VOF function is invented, which treats both mass and energy conservation in conservative form. New techniques include the advection of the interface in a discontinuous velocity field. The proposed algorithms are consistent and elegant, requiring minimal modifications to the existing code. Numerical experiments demonstrate accuracy, robustness and generality. This is viewed as a significant fundamental development in the use of VOF methods to model phase change
Xu, Yang. "Normal impact of liquid droplets on smooth solid surfaces". Thesis, Paris Est, 2018. http://www.theses.fr/2018PESC1099/document.
Under the framework of the LabEx Multi-Scale Modelling and Experimentation of Materials for Sustainable Construction, of Université Paris-Est Marne-La-Vallée, the present PhD thesis aims at modelling and characterizing micro-material designed by impact of molten ceramic droplets. The applications of thin coating materials are surface treatments for sustainable construction such as anti-corrosion, heat barrier, glass treatment or mechanical reinforcement of specific structures.In particular, we focus on the physics behind the liquid droplets' dynamics (the contact area and the contact time between the droplet and surface) by conducting a series of small scale multiphase flow numerical simulations with home-made code Thetis. All simulations are axisymmetric. We have considered variations of initial impact conditions, and studied the influence of inertial, capillary and viscous forces on the droplets' dynamics, especially the maximum spreading diameter, spreading time and the contact time, on solid surfaces. The code is based on Volume-Of-Fluid techniques and introduces an auxiliary smooth function to estimate the local curvature and the normal to the interface. The major reference liquid adopted are the water and the molten ceramic, the water is chosen to validate our code against available experiments at the beginning. The molten ceramic is adopted as it is widely used in thermal spray to built thermal and chemical barriers (anti-oxidant layers) as well as mechanical reinforcements on specific samples. We focus on the cases in which the surfaces are hydrophobic, even if hydrophilic cases are also considered in validation configurations for the sake of generality. Meanwhile, by introducing an energy calculation part in the code, a detailed energetic analysis of the droplet after impact is performed in both the spreading and retraction stage to have a deep understanding of the dynamics inside the droplet.We find the jetting time is inversely proportional to the impact velocity, independent of the contact angle in the early spreading. A new scaling between maximum spreading and spreading time is observed, and agrees well with experimental results. Further, we introduce this scaling into the model based on energy conservation to predict the maximum spreading factor, which provides better prediction on maximum spreading factor than existing literature references. Also a scaling of contact time is proposed in terms of Ohnesorge number and Reynolds number

This PhD thesis is a contribution to the numerical simulation of the plasma sprayedcoating build-up by APS process (Atmospheric Plasma Spraying). This work focuses onthe build-up of a representative volume of the coat considering a great range of phenomenonappearing in APS process such as gas flow properties, kinetic (multiphase flow,wettability) and thermal (heat transfers, thermal contact resistance, solidification) duringthe impact and steaking of particles. An original numerical method, named VOF-SM(Volume Of Fluid - Sub Mesh) is developped. The simulation of the impact of an unsteadyand turbulent ArH2 plasma flow is carried out in order to define the gas flow closeto the wall and heat transferred to the substrate by the plasma. Specific phenomena of theimpact of particles were incorporated into the CFD code (Thétis) and validated independentlyby caparison with analytical solutions, then together combined by the comparisonto a millimeter size impact experimental data. Finally, a study of successive impacts ofYttria-Stabilized Zirconia particles onto a steel substrate was carried out by thermal andkinetic approach similarities to overcome the difficulty of resolving small scales

Chéron, Victor. "Couplage de la méthode de capture d'interface et de particules lagrangiennes pour la simulation de l'atomisation". Thesis, Normandie, 2020. http://www.theses.fr/2020NORMR097.
The study of the liquid jet’s atomization consisting of two immiscible phases is a fundamental research subject. The main motivations linked to the study of these phenomena are the numerous applications resulting from them. For example, in the study of the propagation of a spray within a combustion chamber or for pharmaceutical applications. Their study is carried out by a theoretical, experimental and numerical approach. Each of these techniques faces its own limitations: in the numerical study, the treatment of the droplets resulting from the jet break is a limiting factor due to the size ratio introduced. This thesis manuscript presents the coupling between an Eulerian interface treatment method and a Lagrangian particle transport method, proposing a multi-scale approach to atomization. The numerical solver Archer is used to transport a two-phase flow and to study its evolution, solving the incompressible Navier Stokes equations. The interface separating the two phases is represented by a method combining precision and robustness, the Volume of Fluid/Level-Set coupling. The discretization of the Navier Stokes equations and the transport of the interface is presented in the first part of this manuscript. This introduces the weaknesses of this method due to the multi-scale aspect of the atomized jets: the low precision of the transport of the drops resulting from the secondary atomization. The second section of this manuscript is dedicated to the introduction of Lagrangian drop transport, different approaches are implemented and validated within the computational code Archer. Then, the coupling between the Eulerien and Lagrangian solver, validated from numerical experiments, is introduced. The latter aim to present the methodology implemented to validate the coupling while respecting the conservation of time and mass. This method is then applied to academic cases to introduce the parameterization allowing the junction between the Eulerien and Lagrangien solvers. Finally, the developed method is applied to the study of an atomized jet of crossflow configuration, used in gas turbine or ramjet. The results obtained demonstrate the possibilities related to the Eulerien/Lagrangien coupling, both on the physical and numerical aspects, opening up a model of drop breakup under Lagrangien transport
Canu, Romain. "Développement d'une méthode compressible avec évaporation pour la simulation d'interface résolue dans le cadre de l'atomisation". Thesis, Normandie, 2019. http://www.theses.fr/2019NORMR016/document.
This PhD thesis shows the development of a numerical method for solving two-phase flows with vaporisation. A coupling between Level Set and VOF methods is realised for the interface capturing. In order to solve fluid mechanics equations, a pressure based method is employed and, to decouple velocity and pressure, a projection method is performed. This method allows the implicitation of the acoustic terms and the time step constraint reduction. Liquid and gas are considered as compressible allowing local density variations with equations of state. The vaporisation is computed in two different ways ; a first one where the vaporisation rate is constant and a second one, where this rate is calculated by thermodynamics. Along with this topic, a study on curvature distribution in a liquid injection configuration is realised. This study allows to extend the drop size distribution concept in a spray and to improve available informations on ELSA model. Finally, an other study is performed on thedevelopment of a criterion, based on interface curvatures, which estimates the quality of a simulation

Air Lubrication methods are regarded by the scientific community as the next major technological breakthrough in Naval Engineering to achieve the reduction of drag in commercial vessels. The accurate modeling of the physical phenomena governing the drag reduction mechanisms of Air Lubrication methods, namely, the dynamics of surface tension, the instabilities of the air-water interfaces and air entrainment, are imperative for the design of air-lubricated hulls. To that end, we have implemented to ISIS-CFD several programming tools, interface reconstruction schemes and surface tension modeling. Two new surface tension methods were developed. Both use a global interface reconstruction scheme and are coupled with the compressive discretization volume fraction schemes for the unstructured finite volume formulation that the flow solver ISIS-CFD is based on. The results demonstrate that complicated dynamic interactions of either a single or multiple interfaces can be accurately captured. In the context of a future research study, the proposed approaches could lead to the further enhancement of the modeling capabilities of ISISCFD by introducing a macroscopic air entrainment model and eventually the assessment of different physical effects encountered in lubricated naval vessels using ISIS-CFD

These research work aim to provide a better understanding of coating formation by plasma spraying. They deal with the numerical study of splat formation of which stacking on the substrate leads to the coating. The 3-D model makes it possible to study the impact, flattening and solidification of metal or ceramic droplet on a substrate and to predict the evolution of substrate temperature. It projects the morphology of the splat and possible splashing during the flattening phase. The equations of the model are solved by using the code "Drop" developed by Simulent Inc. The numerical simulations were, first, applied to the impact of millimetric copper and alumina drops impacting on smooth substrates. A preliminary study enabled to determine the optimal dimensions of the grid in the drop and substrate. Then, the effect of the various parameters of impact of the drop (speed, temperature) ; those of the substrate (temperature) and those of the interface (contact angle, thermal resistance) on the formation of the splat was studied

The aim of this study is to propose an adapted model for the simulation of mould filling that must be a compromise solution between computational time and results accuracy. The double difficulty is to take into account the filling phenomenon that is a complex problem due to the presence of free boundaries and to the Glass specificities: viscosity that is highly thermal dependant and high melting temperature that requires taking into account radiation effects. Chapter I is devoted to the melting Glass flow. The numerical libraries Aquilon/Thétis, adapted for solving such type of problems and the thermal coupling between Air/Glass/Walls, has been used. (V.O.F method for front tracking, Augmented Lagrangian/Vector Projection methods for solving Pressure/Velocity coupling). For radiative aspect, different approaches are proposed: equivalent radiative conductivity (Chapter II), direct explicit method for validation (Chapter III) and spherical harmonics method or PN method (Chapter IV). In the Chapter V, the selected PN method is validated through simple cases and is then applied in other cases with convective coupling in complex geometries including semi-transparent inclusions (1D, 2D and 3D, 2D axi-symmetric and non grey medium). A P1 modified version is presented. The results are close to those given by P3 method but with reduced computational time. The main interest of this model is that it can be easily implemented in existing numerical codes: a single stationary second order partial differential equation to solve in 3D

For several decades, an important scientific activity has focused on the numerical, theoretical and experimental hydrodynamics of drops. This work presents numerical results of a single droplet in the gravity field and in non-isothermal conditions. The simulation such a multiphase system is important in both academic and industrial world. This is particularly the case in the field of emulsions, wetting problems and evaporation. To achieve this goal, there are still important algorithmic problems due to the free moving interfaces and the description of capillary effects. Here, a Volume of Fluid technique has been implemented with high order temporal and spatial schemes to preserve the sharpness of the drop interface. The system under consideration is a simplified model consisting in a single water droplet in a continuous paraffin oil phase. These liquids are immiscible and non-compressible and the overall evolution is unsteady. Capillary contributions such as temperature and surfactant dependent surface tension are fully accounted for. This presentation is aimed to show the capabilities of VOF techniques for the simulations of unsteady multiphase systems in non-isothermal configurations. The role of the droplet initial position and temperature field is described with good numerical stability. There are still important problems remaining in the simulation of free interface systems with such a technique. Spurious currents induced by the description of capillarity can in particular come into play. But these latter can be controlled once the droplet average velocity due to drainage becomes large enough

The study of the plasma spraying process is investigated in this work, in particular the interaction between a liquid phase and a plasma flow. Different physical phenomena occureas the jet fragmentation, the liquid vaporization and the particles fusion. The numerical simulation is used to better understand the physical phenomena and is an alternative to experimental measurements, which could be locally difficult to perform because of the measurement techniques limitations and the particular characteristics of the plasma. A compressible two-phase model is developped to take into account the compressible effects of the plasma flow. Validations are realized on academic test cases and on a argonjet. Good agreements are obtained between simulations and theory or experiments. Then different mixtures of plasmagen gas, classically used in plasma spraying, are studied :argon/hydrogen and argon/helium. An analysis of unsteady and turbulent character isled and allows seeing the importance of unsteady effects in these flows. Numerical simulations of the injection of a liquid phase into the plasma flow are realized. The influence of the plasmagen gas nature and the injection type is anlysed. Structures observed by experiments are also obtained by the simulations

This thesis concerns with the Large Eddy Simulations (LES) of fuel sprays in direct-injection engines. Given the high injection velocities of sprays, the resulting turbulent flow may be characterized by energetic intermittent structures at small spatial scales. Therefore, the emphasis in this thesis is put on stochastic simulation of turbulent effects on unresolved scales in the engine relevant conditions. The impact of this effect on spray primary and secondary atomization, on droplets dispersion and evaporation represents the main focus in this thesis. The further assessment and modification of two different approaches, developed recently, was the main objective in this thesis. The first one is addressed to LES-SSAM (stochastic sub-grid acceleration model) approach, in which the Navier-Stokes equations are forced on residual scales. This forcing is given by the Ornstein-Uhlenbeck stochastic process constructed in a way to represent the stochastic properties of the subgrid acceleration, known from the experiment and DNS. In the framework of this approach, with the expression of the acceleration norm modified for the wall-bounded conditions, the first step concerned the simulation of the nozzle internal flow on the coarse grid. The results showed the efficiency of this approach. Another step in this part was to combine LES-SSAM with the interface tracking VOF method in the simulation of the near-field of the spray. The performed assessment of this approach in comparison with measurements and with alternative approaches known from the literature demonstrated a potential of such combination of two methods. The second approach in this thesis, in which the intermittency effects on residual scales are also on target, concerned the stochastic modeling of the secondary breakup, dispersion and evaporation of droplets; introducing the two-way coupling between droplets and a highly turbulent flow. Here, the assessment and further development of stochastic models of droplets represent the main contribution in this thesis. So, the model of the secondary breakup is controlled by the stochastic log-normal process for the viscous dissipation rate. The same stochastic variable is the key variable for the dispersion model of droplets below and above the Kolmogrov scale. The droplet equation of motion for the latter case was modified addressing the significant role to simulation the stochastic direction of the droplet acceleration. Finally, the new stochastic model of the turbulent evaporation, in which the stochastic mixing process is a part of the evaporation model, is also represented in this thesis. The different stochastic models outlined above are assessed in comparison to the state-of-art models available in literature and the experiments of Engine Combustion Network (ECN). The results have shown that stochastic models give a good representation of both macroscopic and microscopic spray characteristics on relatively coarse grids

Bending stiffness and Drapeability are essential material parameters for simulating textile and clothing products. Due to assembling processes garments are showing different appearances through modelling than textile fabrics. This is based on stiffening, which is caused by assembling process and local variations within material’s mass throughout the fabric. Since decades the manual bending stiffness testing device, which is based on Cantilever method, has been known. This device is insufficient because of irregular feed speed of bending sample, the visual determination of reaching and reading the bending length, the little reading precision of the measurable slide (half Millimetre) and the form of the front edge of the sample does not stay linear. Obtaining an exact evaluation of this sample edge is not possible with this device. Extensive experiments have confirmed that these deficits influence the accuracy and the reproduction of the results in a high degree. To remedy these deficits and to obtain an exact description of the material’s behaviour in order to achieve an optimal modelling of the clothing products is the new bending stiffness testing device (ACPM 200) at the ITB of TU Dresden developed. Within the investigations a new method for determining the influence of the seam on the bending stiffness of the adjacent textile fabric will be introduced. The Influence of seams on the drapability of textile fabric is investigated. A static model of Fabric with and without vertical seams is analysed with using the finite element method (FEM)
