进行了一项实验研究，以证明电流体动力学（EHD）技术用于增强制冷剂和制冷剂混合物的管内和外部冷凝的可行性。这项工作旨在产生广泛的实验数据。实验数据用于建立半经验关联式，该关联式可以预测给定制冷剂组和管类型下管内制冷剂的冷凝传热性能。这是建立广义相关性的第一步，需要进行广泛的参数研究。对光滑管和波纹管进行了管内冷凝实验，实验中使用了三种不同的制冷剂，即单组分制冷剂R-134a、近共沸三组分制冷剂R-404a和三组分共沸制冷剂R-407c。 对两种不同增强管的R-134a和R-404a进行了外部冷凝实验。外部冷凝实验中使用的管道为Turbo CII和GEWA-C2。

An experimental investigation was performed to demonstrate the feasibility of the electrohydrodynamics (EHD) technique for the enhancement of in-tube and external condensation of refrigerants and refrigerant blends. This effort was intended to generate a wide range of experimental data. The experimental data were used to formulate semiempirical correlations that could predict the condensation heat transfer performance of the refrigerants inside the tubes for the given set of refrigerants and tube types. This is the first step in formulating a generalized correlation which requires a wide range of parametric studies. The in-tube condensation experiments were performed for a smooth tube and a corrugated tube with three different refrigerants, namely, single-component refrigerant R- 134a, a near-azeotropic three-component refrigerant R-404a, and a three-component zeotrope R-407c. The external condensation experiments were carried out for R-134a and R-404a for two different enhanced tubes. The tubes used in external condensation experiments were Turbo CII and GEWA-C2.
