Numerical Simulation of the Hydrodynamics of a Two-Dimensional Gas-Solid Fluidized Bed by New Finite Volume Based Finite Element Method

In this work, computational fluid dynamics of the flow behavior in a cold flow of fluidized bed is studied. an improved finite volume based finite element method has been introduced to solve the two-phase gas/solid flow hydrodynamic equations. this method uses a collocated grid, where all variables are located at the nodal points. the fluid dynamic model for gas/solid two-phase flow is based on the two-fluid model where both phases are continues and fully interpenetrating. for the gas and solid phases the navier-stokes equation based on the concept of local average is obtained. results are verified against experimental data reported in the literature.
