Abstract

A numerical scheme based on Boundary Domain Integral Method (BDIM) is being developed to model the bubbling behaviour of fluidized beds by using the Eulerian approach. Each phase is described by a modified Navier- Stokes equation. While modified Helmholtz fundamental solution has been used for the kinematics, the elliptic diffusion-convective one has been used for the kinetics of the both components motion. A gas-phase is described by its physical properties, but the solid-phase needs additional physical mod- els. The most promising set of the equations in the sense of fast numerical convergence is presented in present work. 1 Introduction Fluidized multiphase reactors are of increasing importance in nowa- days chemical industries. Although the tools for applying sing
