对制冷剂经喷嘴并伴随有相变的的流动问题进行了实验研究。实验结果表明，在相同出口压力下，随着喷嘴入口压力的提高，制冷剂的流量近似线性地增加。
An experimental study of the flow problem of refrigerant passing through a nozzle with phase changes was carried out. The experimental results show that the refrigerant flow increases approximately linearly with the increase of nozzle inlet pressure at the same outlet pressure.
