Interaction Force between Solid and Liquid Phases in Two-Phase Flow

Abstract

It's necessary to consider the interaction force between solid-and liquid-phase in two-phase flows. In this paper, the governing equations of solid-liquid flows are established by space average and Reynolds average mothers. The drag force of particles is evaluated on the basis of experiments of solid-liquid flow in vertical tube. The results show that the accumulation effect of particles on drag force is closely to the particles concentration and relative density of two-phase flow.
