A meta-stable effect on a subcooled critical flow in a nozzle and an orifice was investigated. For an investigation of the meta-stable effect, two homogeneous nucleation models, e.g., the Alamgir and Lienhard’s model and the Elias and Chambre’s model, and one conventional isentropic model, e.g., the Henry and Fauske’s model, were compared with respect to a previous test data performed by Sozzi and Sutherland. From comparisons of throttle pressures among the nucleation models and the isentropic model, the test data and the Henry and Fauske’s model were lying between the two homogeneous nucleation models. Throttle pressures predicted by the Alamgir and Leinhard’s model provided a lower bound and an upper bound done by the Elias and Chambre’s. A further discussion for a meta-stable effect on critical flow in orifices using the author’s previous data was also presented.

甲元上喷嘴中的过冷临界流量和节流孔-stable效果进行了研究。对于该调查荟萃稳定版的效果，二均相成核机型，例如，阿拉姆格和林哈德的模型和埃利亚斯和单人间的模型，和一个传统的熵模型，例如，亨利和福斯克的模型，分别相对于以前的相比， Sozzi和Sutherland执行的测试数据。通过比较成核模型和等熵模型之间的节流压力，测试数据以及亨利和福斯克模型位于这两个均相成核模型之间。Alamgir和Leinhard模型预测的节气门压力提供了Elias和Chambre的上限和下限。关于meta的进一步讨论还使用作者先前的数据对孔中的临界流量产生了稳定的影响。
