含油制冷剂R600a管内两相流动摩擦压降研究
|
摘要
基于文献含油制冷剂R600a两相流动摩擦压降实验数据,采用文献中6种关联式模型对含油制冷剂R600a两相摩擦压降的实验数据进行预测判断。结果表明:油影响因子模型Schlager关联式和Eckel关联式的预测值与实验值平均绝对偏差分别为27.3%和24.4%;混合物性的两相增强因子模型Zurcher关联式和Hu关联式的预测值与实验值的平均绝对偏差分别为33.8%和34.0%,上述关联式预测值普遍低于实验值。
Based on the experimental data of the two-phase flow frictional pressure drop of R600 a and oil mixture,six correlation models mentioned in the literature were used to make predictions about the experimental data of the two-phase frictional pressure drop of R600 a and oil mixture. Results show that as for the factor model of the oil's impact, the average absolute deviation between the predicted value and the experimental value of the Schlager correlation model and that of the Eckel correlation model are 27.3% and 24.4% respectively. As for the two-phase enhancement factor model of the mixture's properties, the average absolute deviation between the predicted value and the experimental value of the Zurcher correlation model and that of the Hu correlation model are 33.8% and 34.0% respectively. The above predictive values made with the correlation models are generally lower than the experimental data.
