On a Dirichlet problem related to anisotropic fluid flow in bidisperse porous media

Abstract

This paper is concerned with the study of a Dirichlet boundary value problem for a system of two coupled anisotropic Darcy-Forchheimer-Brinkman equations on a bounded Lipschitz domain in \mathbb{R}^{n}=\left( 2,3\right). Using variational methods and fixed point techniques, we obtain a well-posedness result in  L^{2}-based Sobolev spaces for sufficiently small data. As an application, we investigate numerically the lid-driven flow problem in a square cavity saturated with a bidisperse porous medium and analyze the effect of various physical parameters on the fluid motion.
