Baudry, Cécile. "Des invariants pour une équation elliptique-parabolique des milieux poreux : étude théorique et applications numériques." Paris 13, 2010. http://www.theses.fr/2010PA132006.
In this thesis, we study some invariants for selfsimilar solutions of an elliptic-parabolic equation, which is used for the modelling of water flows in saturated-unsaturated porous medium. We look into intermediate asymptotics, in space and in time, for Richards’ equation in 1D in a semi-infinite domain. At the initial time, a finite part is saturated and an infinite one is unsaturated. Indeed, selfsimilar solutions are solutions of problems with specific initial and boundary conditions. According to Barenblatt and Zel’dovich, these selfsimilar solutions are also good approximations of more general problems, with different boundary or initial conditions. Then selfsimilar solutions are called respectively intermediate asymptotics in space and in time for the general problem. We can do these approximations if the general problem and the selfsimilar problem check the same invariant. We underline it is only a necessary condition. This manuscript is divided into six chapters. The first one recalls the physics of the problem. The second and the third chapters deal with the theoretical and numerical aspects of a special case: the heat equation. The last three chapters concern Richards’ equation; we study intermediate asymptotics in space and in time after a bibliography about existence and unicity for this equation

The main object of this thesis is an evolution problem in L1(Rd) of the type ∂tu(t, x) =1/2xΔβ(u(t, x)), (t, x) ∈ ]0, T ] × Rexpd. (PDE). In our work, we have investigated some theoretical complements related to the (probabilistic) representation of that equation, via a non-linear diffusion process, when the coefficient β is discontinuous or in the case β(u) = um, 0 < m < 1 (“fast diffusion equation”). Even though the theoretical results concern essentially dimension d = 1, we have also establi- shed a uniqueness theorem for a multidimensional Fokker-Planck type with measurable, possibly unbounded and degenerated coefficients. This has been an important tool for the probabilistic representation. We have also established some density estimates (via Malliavin calculus) of the solution of an SDE with smooth unbounded coefficients, with bounded derivatives of each order, uniformly with respect to the initial condition. The main objective of the thesis consists however in the implementation of an interactive particle system algorithm, which approaches the solutions of the PDE. Comparison with recent deterministic numerical techniques have been performed. This has been done in the one dimensional and multidimensional cases

By using the mathematical techniques of homogenization and by starting from the Navier-Stokes equations, we model the injection of fuids in porous medium in three different cases. - First, in the case of a compressible fluid: we recover the model of Aronson. -then in the case of an incompressible fluid injected in the porous medium filled with another incompressible fluid. We demonstrate that the interface is determined by a problem of Riemann and that its average speed is linear. We show that the nature of the interface is essentially de fined by the coefficient of mobility of both fluids. We validate the model thanks to an experience of injection of resin in a porous medium. We use our model to interpret a known physical phenomenon but in our knowledge never explained in satisfactory way: the headway of the interface along the walls of the porous mould in the case of the injection of a very sticky fluid. - Finally we consider the previous case when the injected uid is condensable. We demonstrate again that the interface is determined by a Riemann problem but that its speed goes asymptotically towards zero. We validate our model with an experience of vapor injected in some concrete. We give a new explanation to a phenomenon classically called " phenomenon of cork " and observed in this type of experience

In this thesis, we study two completely independent problems. The first one focuses on a simple mathematical model of thin films delamination and blistering analysis. In the second one, we are interested in the study of the porous medium equation motivated by seawater intrusion problems. In the first part of this work, we consider a simple one-dimensional variational model, describing the delamination of thin films under cooling. We characterize the global minimizers, which correspond to films of three possible types : non delaminated, partially delaminated (called blisters), or fully delaminated. Two parameters play an important role : the length of the film and the cooling parameter. In the phase plane of those two parameters, we classify all the minimizers. As a consequence of our analysis, we identify explicitly the smallest possible blisters for this model. In the second part, we answer a long standing open question about the existence of new contractions for porous medium type equations. For m>0, we consider nonnegative solutions U(t,x) of the following equationU_t=Delta U^m.For 0

The aim of this thesis is the study of two problems of flow through porous media. In the first and the second chapter we study in the general framework of the homogenization method the flow of a viscous fluid through an elastic thin porous media. After the proof of the convergence of the homogenization process by using the two-scale convergence method it is possible to take the limit as the second small parameter (who caracterize the thickness of the solid part) tends to zero. We obtain a viscoelastic media with fading memory. We consider the two classical cases, when we have a Stokes flow in the fluid part and when we have a Navier-Stokes flow in the fluid part. In the third chapter we study a double porosity model in a double periodicity media. From a mechanical point of view this model represents a fracturated porous media. From a mathematical point of view we study a Neumann problem with double periodicity. We prove existence and unicity for such a problem and using the three-scale convergence method we obtain the homogenized equation and the homogenized coefficients. The result we obtain is a Darcy law at the macroscale and this show us that, at least in the steady case, both the double periodicity model and the double porosity model are the same

In this work, we study fluid flows through a porous medium with leaky boundary conditions. In the first chapter, the fluid is governed by a linear Darcy's low. The second chapter is about a unbounded dam. In the third chapter, we extend our results to the case of a maximal monotone graph. In the last chapter, the fluid is governed by a nonlinear Darcy's low. In this thesis, we investigate questions of existence, uniqueness and shape of the free boundary

This thesis aims to show that the numerical simulation of heat and mass transfer in porous media can be effectively treated by a numerical program which is based on a space discretization of spectral type. The spectral method is optimal in the sense that the error obtained is only limited by the regularity of the solution. The starting point of this study is the system of nonlinear unsteady Darcy equations that models the unsteady flow of a viscous fluid in a porous medium when the permeability of the medium depends on the pressure. The second problem which we study models transfer of heat in a porous medium which is described by Darcy equations coupling with the heat equation. In the last part, the concentration of mass is taken into account in the medium, we describe a nonlinear problem that models unsteady transfer of heat and mass in porous media. In the three proposed problems, the results of the existence and the uniqueness are established. Then the corresponding discrete problems are described. We prove the error a priori estimates and we confirm the theoretical study with numerical results
