Was ist Lattice-Boltzmann


The aim of this talk is to provide an introduction to the Lattice Boltzmann method (LBM) as a numerical tool for fluid flow simulations in modern computational fluid dynamics (CFD). After discussing some historical background, we focus on the implementational aspects and the numerics running behind the LBM and will briefly show how one could recover the macroscopic flow equations from the mesoscopic LB equation using multi-scale analysis. Finally, we will present some interesting applications where the LBM is used to resolve problems ranging from 2D simple flows to multiphase flows as well as complex 3D flow of multicomponent mixtures through porous media.
