In this paper we present a parallel implementation of a 2D numerical model for the solution of a transient density driven flow in porous media. The physical processes involved are multiscale, therefore computation time are usually long, thus a special effort has been made to speed-up computations by using parallel architectures. As most of the CPU time is(More)
This paper treats a one dimensional phase-change problem, ’ice melting’, by a vertex-centered finite volume method. Numerical solutions are obtained by using two approaches where the first one is based on the heat conduction equation with the basic grid (improved by introducing a new adaptive mesh technique), latent heat source approach (LHA), while the(More)
In this paper, we study an inverse problem consisting in the determination of the mechanical properties of a layered solid elastic medium in contact with a fluid medium by measuring the variation of the pressure in the fluid while propagating a seismic/acoustic wave. The estimation of mechanical parameters of the solid is obtained from the simulation of a(More)
Using the μ(I) continuum model recently proposed for dense granular flows, we study theoretically steady and fully granular flows in two configurations: a plane shear cell and a channel made of two parallel plates (Poiseuille configuration). In such a description, the granular medium behaves like a fluid whose viscosity is a function of the inertia. In the(More)
A new stability investigation method based on normal modes of linearized free-surface perturbations is presented. Stability criteria, for each temporal schemes, are deduced from this method via a symbolic computation of the two eigenvalues of the amplification matrix, allowing us to choose the optimal time step in a straightforward manner. Moreover,(More)
Maxwell Stress Tensor (MST) method is investigated in this study to quantify the degree of approximation made with the point–dipole method in respect to dielectrophoresis (DEP) in micro–devices. Latex particles and biological cells immersed in aqueous buffers of various conductivities are considered. The two methods (point–dipole and MST full approaches)(More)
The rise of a buoyant bubble and its interaction with a target horizontal wall is simulated with a 2-D numerical code based on the Boundary Element Method (BEM). Developed from a viscous potential flow approximation, the BEM takes into account only the part of the energy dissipation related to the normal viscous stresses. Hence, a simple analytical model(More)
