Testo completoThe system modeling a two incompressible phase flow with high porosity in an oil-field is governed by the law of Darcy-Brinkman. The velocity of filtration of Darcy leads to an elliptic equation in pressure and a degenerate parabolic equation in saturation. This system is widely used in porous media. In this thesis, we are interested in the modification of Brinkman which consists in modifying Darcy’s law by adding a viscosity disspative term. This system leads to an elliptic equation in pressure and unstandard parabolic equation in saturation regularized in time. First, we are interested in the mathematical study of the Darcy-Brinkman’s system and in the regularity of the solutions. To simulate numerically the solutions of this problem, we study the convergence of a finite-volume scheme on an admissible mesh for a homogeneous porous media. Then, we propose a combined method of finite volume - nonconforming finite element type to deal with the anisotropic of the media. In the second part of this thesis we deal with the compressibility of the fluids. We suggest a model of Darcy- Brinkman to describe the compressible monophasic case. We show that this model is well posed in dimension one in the whole space. Then, under the hypothesis of Bear, we also show that this model is well posed in dimension d ≥ 2

Testo completoThe formation of particles cake on the surface of the filter constitues one of the limiting phenomena of all the microfiltration operations. Progressively with its growth, this deposit, which adds an additional resitance to the fluid flow, reduced gradually the energetic efficiency of the filter system. The purpose of this work, is to characterize the influence of the hydrodynamic and physicochemical conditions on the morphology and the transport properties of the cake. Our study is carried out on a field made up of one or more unit elements representative of a filter surface models, provided with boundary periodic conditions. Moreover, in a first approaches quasi two-dimensional, the field is restricts with a Hele-shaw cell of which the thickness is equal to the particle diameter, so that the model of Darcy applies to the totality of the field. The particles are injected one by one starting from an initial position by chance selected and describe trajectories which take account of the structure of the flow and the physicochemical interactions of type DLVO with porous surface and the particles already deposited. The flow of Darcy is recomputed once the particle deposited

Testo completoThe problem of the porous square cavity is extensively used as a common benchmark case for Natural convection (NC) problem in porous media. It can be used for several numerical, theoretical, and practical purposes. All the existing high accurate solutions are developed under steady-state conditions. However, it is well known that the processes of NC in porous media occurs naturally in a time-dependent procedure, as boundary conditions can be variable in time. Also, the convergence of the steady-state solution is known to be difficult. To overcome this difficulty, the steady-state solution is often simulated as a transient solution that evolves until reaching the steady-state condition. These time-dependent modes are very efficient to detect the effects of the parameter variations on the physical process of NC, especially for the subject of interest in this thesis: the domain inclination level and hot wall temperature variation in time. For this purpose, three goals are identified in this Thesis: 1. Developing a time-dependent solution of natural convection in porous media using the Darcy model in two modes: Transient and unsteady. 2. Investigating the time-dependent behavior of natural convection in porous media having the domain inclination level as a variable parameter in two modes: Transient and unsteady. 3. Developing a time-dependent solution of natural convection in porous media using the Darcy-Lapwood-Brinkman model in two modes: Transient and unsteady. To do so, according to the high accuracy in the simply connected domains, one of the Galerkin spectral weighted residual method is chosen to develop a space-time dependent solution for NC problem in a square porous cavity. Applying the Fourier-Galerkin (FG) procedure, two configurations dealing with transient and unsteady regimes are considered where each solution is derived for a wide range of Rayleigh numbers with other special conditions. This work of thesis is explained in details as five chapters.The NC physical process with the time-dependent variations is described in the transient mode to reach the steady-state solution and for the unsteady mode during a one period using periodic sinusoidal boundary conditions on the cavity hot wall. Finally, the work of this thesis is described in details in five chapters; while the sixth and last chapter is devoted to the summary and conclusion.The results in this thesis work provide a set of high-accurate data that are published in three papers to be used for testing numerical codes of heat transfer in time-dependent configurations

Testo completoThe hyporheic zone is a bioreactor which can influence the biogeochemical functioning of fluvial hydrosystems. In this work, quantification of its role on water and solutes fluxes in hydrosystem of large alluvial floodplains was made by modelling approach. The proposed model was applied and validated using data previously measured on experimental sites of Freienbrink (Germany), Hers and Garonne (France). The complete model consists of two additional components: a hydrodynamic component (horizontal 2D Saint Venant equations for river flow and 2D Dupuit equations for hyporheic zone flow) coupled with a reactive solute-transport component for dissolved forms of mineral nitrogen and organic matter. The conclusions highlight the importance of transient exchanges between stream and hyporheic zone which facilitate water storage and denitrification processes activation

Testo completoIn the present work, we study the effect of the action of mechanical vibration on the convective motion in mono and multi-component fluids in the presence or in the absence of gravity. In the framework of the Boussineq approximation, the induced convective motion due to the temperature field in the presence of gravitational and vibrational fields are studied. In the first part of this work, the linear and weakly non-linear stability analysis of Horton-Rogers-Lapwood problem under the effect vertical vibration (parallel to the temperature gradient) has been carried out. Two different approaches (time-averaged and direct methods) are used to study the thermal stability analysis of this problem. By applying the results obtained from the scale analysis method to the coefficients of the Mathieu equation, the criteria for comparing the results from these two stability analysis approaches are found. In the second part of this work, the influence of directions of vibration of high frequency and small amplitude on the onset of Soret driven convection is addressed. The linear stability analysis in an infinite horizontal layer filled by a binary mixture is performed. The stability of quasi-equilibrium solution for an arbitrary direction of vibration in the presence or in the absence of gravity for long wave mode is then examined. For this case, an analytical relation giving the critical parameter is found. .

Testo completoHydrocarbon migration modeling in sedimentary basins aims to localize and to quantify hydrocarbon accumulations in geological formations in order to estimate their petroleum potential. In this thesis, we study “Darcy” migration models and also simplified migration models such as “ray-tracing” and “invasion percolation”; the purpose is to conduct a critical analysis and to offer improvements while providing a guide for a relevant use on case studies.We start by a review of migration mechanisms from the pore scale to the basin scale, then we present each model.In a following part, we propose two invasion percolation algorithms: the first one is suited to structured grids, the second one allows to take better account of unstructured grids.In a third part, we take an interest in the comparison between the different models and particularly between “Darcy” and “invasion percolation” approaches. First we devote our attention to numerical aspects supported by several use cases; then we realize a formal comparison by studying the asymptotic limit of the “Darcy” model large time solution. Afterwards, we present several applications including the study of a 3D real case in complex geometry.Finally, we conclude this work with two articles. The first one shows an evolution of “Darcy” models by using the method of local grid refinement with an illustration on a case study from northern Kuwait. The second one synthesizes the main results on “Darcy” and “invasion percolation” methods
