The Research Progress on Pressure Drop of Rotating Packed Bed

摘要

Rotating packed bed is a new high efficient equipment for multiphase flow transference, it has been widely used in chemical separation and preparation of nano-materials. The gas pressure drop of RPB is one of important indicators which are used to measure performance of RPB. In this paper, the experimental and simulative progress of research on the gas pressure drop at home and abroad in recent years is reviewed. All kinds of gas pressure drop experiments and simulations of counter-flow RPB, cross-flow RPB are introduced and compared, followed with the analysis of the progress, existing problems, the trend and emphasis.
