Abstract

In this work a fictitious domain method is presented for the direct numerical modeling of 3D particulate flows. The flow field is described by the nonstationary incompressible Navier-Stokes equations and the motion of the particles is modeled by the Newton-Euler equations. For the computation of the two-phase flow the multigrid Finite Element Method (FEM) is coupled with the Discrete Element Method (DEM). The phase coupling is performed in an explicit manner by applying rigid body motion constraints. The combination of fast FEM solvers with efficient search algorithms for the DEM allows 3D simulations with a large number of particles.
