Calculation of the Drag of Dispersed Particles : No. 1 Oseen's Approximation and the Simple Cell Model Method

Abstract

The drag of a flow through uniformly dispersed spherical particles is predicted. The results are useful for studying the dynamics of multiphase flows containing dispersed particles and fluidized beds. In analyzing the flow, the many body effect on the drag is considered by utilizing the simple cell model method. The basic equation of motion of fluid is simplified by Oseen's approximation. The drag coefficient is computed as a function of the volume fraction of particle phase and of the Reynolds' number of flow.
