The lattice Boltzmann method (LBM) is applied to simulate three dimensional flows through ceramic matrixes. The simplified structures are generated randomly by computer. As a test of the lattice Boltzmann code, the relation between pressure drop and superficial velocity in porous medium is obtained which agrees well with Darcy’s Law. Local velocities of different pores are also analyzed. The velocity distributions are approximate to parabolas. Calculation results show that the Darcy number increases along quadric curves with the increase of sphere diameter and porosity.
Keywords:Ceramic Filter Media, Lattice Boltzmann Method, Three dimensional Flow, Simulation.
