Abstract: This paper investigates the seepage flow through idealized particle assemblies comprised of spherical elements. Comparisons between an analytical solution and numerical approximation using the Discrete Element Method (DEM) with coupled hydromechanical interaction between the particles and the pore fluid are provided. In the coupled flow DEM, the fluid motion is treated at the macroscopic scale by solving the local averaged Navier-Stokes equation, while the particle interaction is treated at the microscopic scale. The numerical solution is compared with the classical analytical solution in terms of quantity of flow and the pore pressure distribution.
