Abstract

A novel numerical scheme based on the boundary domain integral method (BDIM) for the numerical simulation of gas-solid particle flows is presented. Eulerian approach in terms of velocity-vorticity variables formulation is used. Each phase is described by a modified Navier-Stokes equation in- cluding interphase momentum exchange. With the vorticity vector Upi rep- resenting the curl of the velocity field Vpi both phases motion computation scheme is partitioned into its kinematic and kinetic aspect. The additional equation from the drift flux theory is necessary to compute volume fraction. Main advantage of the proposed BDIM scheme is reduced number of physi- cal models derived from the kinetic theory of granular flows for description of the solid phase. Two-phase two-component results are studied on two- phase gas-solid particl
