CFD simulation of flow and mixing characteristics in a stirred tank agitated by improved disc turbines
文献摘要：
To reduce the power consumption and improve the mixing performance in stirred tanks,two improved disc turbines namely swept-back parabolic disc turbine(SPDT)and staggered fan-shaped parabolic disc turbine(SFPDT)are developed.After validation of computational fluid dynamics(CFD)model with exper-imental results,CFD simulations are carried out to study the flow pattern,mean velocity,power con-sumption,pumping capacity and mixing efficiency of the improved and traditional impellers in a dished-bottom tank under turbulent flow conditions.The results indicate that compared with the com-monly used parabolic disc turbine(PDT),the power number of proposed SPDT and SFPDT impellers is reduced by 43％and 12％,and the pumping efficiency is increased by 68％and 13％,respectively.Furthermore,under the same power consumption(0-700 W m-3),the mixing performance of both SPDT and SFPDT is also superior to that of Rushton turbine and PDT.
