非共沸制冷剂R417A在水平光滑管内的沸腾传热

Numerical Simulation of Zerotropic Refrigerant Mixture R417A Evaporating in Horizontal Smooth Tube

应用一种快速、准确的隐式格式迭代数值计算方法 ,对非共沸制冷剂 R41 7A在水平光滑管内的蒸发过程进行了数值模拟。通过应用纯质的传热公式计算后与实验值相比较 ,数值计算结果高于实验值。

In this paper, an implicit numerical method is used to simulate the evaporation of zerotropic refrigerant R417A in horizontal smooth tube. Local heat transfer coefficient is calculated with correlations of pure refrigerant. The results of simulation are higher than the one of experiments.
