摘要: 为提高外驱式旋转压能交换器性能,设计了转子流道倾斜式的外驱式旋转压能交换器,以能量回收效率和体积混合率为性能指标,利用商业CFD软件Fluent对模型求解计算,并与直流道外驱式旋转压能交换器模拟数据对比分析。结果表明,处理量相等的情况下,能量回收效率和体积混合率均随转子转速的升高而降低;同一转速下,转子倾斜角度改变,能量回收效率变化不超过0.04%,而对体积混合率有明显影响。研究结果对于提高外驱式旋转压能交换器设备性能具有一定指导意义。

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
