An experimental investigation of a Ranque-Hilsch vortex tube has been performed. The investigation focuses on the effects that pressure magnitude, pressure drop and pressure ratio have on the temperature drop between the inlet and the cold outlet. The Ranque-Hilsch vortex tube used in the experiments was designed through consideration of a large body of experimental data consolidated from existing literature. Experiments are conducted for cases of constant cold exit pressure (0.31 [MPa]), constant pressure drop between the inlet and cold exit (0.31 [MPa]), and constant pressure ratio between the inlet and cold outlet (2.0). From the experimental data collected, the temperature drop was found to be best correlated to the ratio of the inlet and cold outlet pressures, suggesting that the process could be characterized as polytropic. Results for each case were reported in terms of recovery temperature and static temperature to illustrate the importance of interpreting the dynamic component of temperature in the results. The reported results show that for a pressure ratio of 2.0, the maximum recovery temperature drop is 13.96 [K], whereas the corresponding static temperature drop is 12.25 [K].

已经对Ranque-Hilsch涡管进行了实验研究。研究集中在压力大小，压力下降和压力比对入口和冷出口之间的温度下降的影响上。实验中使用的Ranque-Hilsch涡流管是通过考虑从现有文献中合并的大量实验数据而设计的。针对恒定的冷出口压力（0.31 [MPa]），入口和冷出口之间的压力降恒定（0.31 [MPa]）和入口和冷出口之间的压力比恒定（2.0）的情况进行实验。从收集的实验数据中，发现温度下降与入口压力和冷出口压力之比最相关，这表明该过程可以描述为多向性。报告每种情况下的结果，包括恢复温度和静态温度，以说明解释结果中温度的动态成分的重要性。报告的结果表明，对于2.0的压力比，最大恢复温度下降为13.96 [K]，而相应的静态温度下降为12.25 [K]。
