Three-dimensional numerical model of internal erosion

Abstract

The purpose of this study concerns the establishment of three-dimensional numerical simulation of the coupling between fluid flow and internal erosion within a porous medium. In order to properly investigate suffusion process in porous media, we present a finite volumes method using explicit scheme for solving advection–dispersion–deposition equation on three-dimensional grids. The accuracy and the robustness of the proposed finite volume method are assessed by means of various numerical test cases and validated by the adjustment of experimental results.
