Lattice-Boltzmann simulation of gas-particle flow in filters
The approach used for the computations of fluid phase is based on an approximation of the Boltzmann equation, called the lattice-BGK approach. The new kind of boundary conditions fit with the second-order accuracy of the hydrodynamical no-slip conditions on a surface of arbitrary form lying between the nodes of a regular lattice. This simulates in an effective way the viscous incompressible flow with complex boundaries at small Reynolds number. The motion of the solid phase is calculated by means of a Lagrangian approach. Results are presented for different Stokes numbers to study the influence of hydrodynamics on particle deposition.
