| 摘 要： | 首先从理论上建立计算涡流二极管的性能比的模型，并进行了实验验证。实验结果表明：理论预测的性能比与实验结果误差不大，并且涡流二极管的结构参数(r1／r0)是影响其性能比的最主要参数。

| Abstract: | Based on the characteristics of the flow in the vortex diode, the parameter, called the performance ratio, which can describes the properties of the vortex diode, was defined as the ratio of the reserved flow resistance coefficient to the forward one. According to the hydrodynamic calculation of the flow resistance coefficient, the performance ratio can be calculated from the known geometric parameters of the vortex diode, and it shows that the parameter, (ri /r0), has the dominant influence on the performance ratio. At the same time, the performance ratio was experimentally determined by relating the measured forward flow pressure drop and reversed flow pressure drop to the flow rate. The results show that the calculated performance ratio of the vortex diode is in good agreement with the experimental values. |
