Parallel Single- and Multiphase CFD-Applications Using Lattice Boltzmann Methods

The lattice Boltzmann equation [1] is a particularly effective model for the simulation of complex problems like transient 3D single- or multi-phase flows. We give a short overview with respect to efficient data structures and put special emphasis on vectorization aspects and the parallelization for a LB kernel based on topologically unstructured grids. Three engineering applications are presented: The unsaturated multi-phase flow in soil probes, two-phase flow in a bioreactor and turbulent flow over a surface mounted cube.
