| 摘 要： | 旋转式压力能交换器是利用正位移原理工作的流体能量回收装置,核心部件是沿周向开有轴向贯通孔道的转子,其通过转子孔道内形成的液柱活塞传递能量并控制掺混率.在试验研究基础上,利用数值模拟手段,建立了孔道内流体质量传递模型,说明了液柱活塞的形成过程,并分析了影响液柱活塞的主要因素.结果表明系统流量和转子转速对液柱活塞形成和运动规律有较大影响,液柱活塞能够根据流量变化和转子转速进行自适应调节,因此能够稳定地在孔道内往复移动以保证获得最大的容积利用效率.

| Abstract: | Rotary pressure exchanger(RPE) is a kind of liquid energy recovery equipment based on the positive-displacement principle.The key component of RPE is rotor with plurality of ducts around axis.The liquid piston formed in ducts transfers energy and controls mixing rate.The theoretical model of mass transportation in ducts during mixing process was set up based on experiments.By numerical simulation,the formation process of liquid piston is discussed,and the main factors affecting the liquid piston performance... |
