Abstract
In this paper, the flow law of gas-liquid-solid three-phase flow was studied in the disc pump internal, established a set of numerical simulation method that calculated multiphase flows of disc pump internal. Finally the structure of the disk pump impeller was improved, and designed a new disc pump with multiple-blade structure, through numerical simulation calculation for the gas-liquid-solid three-phase flow of the disc pump internal, mastered change rule of fluid pressure and speed in disk pump internal, obtained relation curves between the different solid phase particle concentration with different gas phase concentration and the head with the efficiency of the pump. The head of the new disc pump was significantly improved by analyzing the disc pump head curve and the actual application.
