两相流动特性研究

Characteristic Study of Two-Phase Flow

建立了用于毛细管二相流实验研究的横拟实验台,分析了制冷剂F—11在毛细管中的两相流动特性,进行理论计算,给出了毛细管流量和有关物理量之间的特性曲线,实验结果与理论计算的误差为15％,可作为空调与制冷设备设计时参考。

This paper presents a simulating experimental stand for the study of capillary experiment and the analysis of two-phase flow characteristics of refrigerant F-11 (freon-11 ) in a piece of capillary.Based on the basic differential coupled equations and the experiment,the function curves about the transportation capacity and the relative physical measures are given.A comparison is made between the theoretic calculation and the experiment results of capillary two-phase flow at the same
