Chapter 3 - Coupled methods

Abstract

In this chapter, we introduce the basic schemes of CFD-DEM coupled algorithms. Three representative types of coupling approaches, the large eddy simulation – discrete element method (LES-DEM), the direct numerical simulation – discrete element method (LES-DEM), and the lattice Boltzmann equation – discrete element method (LBE-DEM) coupled methods are introduced in details. One of the typical multiple schemes, the lattice Boltzmann method – immersed boundary method – discrete element method (LBM-IBM-DEM) is also introduced to demonstrate the capability of multiple schemes for simulating complex gas-particle systems.
