Lattice Boltzmann Simulations of Complex Multiphase Flows
This paper presents simulation results for two classes of multiphase problems obtained using Lattice-Boltzmann approaches. The first part of the paper deals with gas-particle flow investigated by the Duisburg group. A detailed numerical investigation of particle deposition on a complex geometry is presented and values of collection efficiency of dynamically obstructed filters are obtained. The second part of the paper (contributed by the first two authors) investigates air-water flow in a porous medium and, to the authors knowledge, presents for the first time the qualitative reconstruction of a hysteresis curve for a realistic soil geometry obtained by X-ray tomography.
