Abstract

Abstract: Herein, an external-drive rotary pressure exchanger with tilted rotor channel was proposed to improve the performance of the exchanger. Energy recovery efficiency and volume mixing ratio were used as performance indexes. We used commercial CFD software Fluent to simulate the model and compared it with the simulation data of a DC out-of-channel-drive rotary pressure energy exchanger. Results showed that when the processing volume was equal, both the energy recovery efficiency and volume mixing ratio decreased with rotor speed increasing. Under the same rotor speed, with the rotor incline angle changed, the energy recovery efficiency changed to no more than 0.04%. The rotor incline angle had a significant impact on the volume mixing ratio. The results can be a guidance for improving the performance of external-drive rotary pressure exchanger.

Key words: rotary pressure exchanger, rotor incline angle; numerical simulation, energy recovery efficiency, volume mixing ratio
