Abstract

In the present study the numerical solution of gas-solid particle flow using the Boundary Domain Integral Method (BDIM) is investigated. A program is being developed to model the hydrodynamics of fluidized bed systems by using the Eulerian approach. Both phases are treated as separated, in- compressible, continuous and fully interpenetrating fluids. Each phase is described by a modified Navier-Stokes equation including interphase mo- mentum exchange. With the vorticity vector Upi representing the curl of the velocity field Vpi both phases motion computation scheme is partitioned into its kinematic and kinetic aspect. Therefore the additional equation from the drift flux theory is necessary to compute volume fraction knowing the velocity fields. Main advantage of the new BDIM scheme is reduced number of additiona
