Abstract
This paper deals with the numerical simulation of threedimensional gasparticle flow through filters. Typical for filter flows is the deposition of particles on the surfaces of filter material, resulting in irregular shapes of surfaces, which in interaction with the flow field influence the next particle deposition. The investigations have shown that latticegas approaches perform very well for such interactive flow around complex surfaces. The approach presently used for the computations of fluid phase is based on an approximation of the Boltzmann equation, called the latticeBGK approach. The new kind of boundary conditions fit with the secondorder accuracy of the hydrodynamical noslipconditions on a surface of arbitrary form lying between the nodes of a regular lattice. This simulates in an effective way the viscous incompressible Bow with complex boundaries at small Reynolds number. The motion of the solid phase is calculated by means of a Lagrangian approach. This solution concept is demonstrated for gasparticle Bow througha model of a fibrous filter. Results are presented for different Stokes numbers to study the influence of hydrodynamics on particle deposition. (C) 1997 Elsevier Science Ltd.
