摘要
文中采用雷诺应力模型(RSM)对涡流二极管泵内部流场进行三维数值模拟,阐述涡流二极管内部流场及高阻产生机理,将内部流动近似为Rankine涡并进行验证,分析了切向入口压力变化对流动特性的影响,结果表明:入口操作压力超过一特定限度后中心区域将出现较大的回流现象,这将有助于提高涡流二极管性能。
The Reynolds Stress Model （RSM） was used to simulate the 3D internal flow of the vortex diode pump, and the flow field was described and the high resistance characteristics were explained. The internal flow was assumed to be like the Rankine vortex which was confirmed by the simulation data. The effect of different tangential pressures on the flow character was described in detail. The results showed that there would be backflow in the center export area when the inlet pressure exceeded a certain point which helped to raise the performance of the vortex diode pump.
