低温气液两相流数值计算

Numerical Simulation of Cryogenic Two-Phase Flow

低温工质两相流动在很多场合都存在 ,研究深冷剂在两相流动时参数的分布有着很重要的作用。文中采用一维均相流模型对液氮循环流动过程进行稳态数值模拟 ,得到了循环流动过程中液氮含汽率、压力和温度沿管程方向的分布情况 ,并对由于不同回路条件引起的不同结果进行了分析。

This paper simulates the natural circulation flow of liquid-nitrogen by using one-dimensional homogenous two-phase flow model, the computation results consist of the parameter (e. g. Temperature, quality, pressure, flow rate, etc.) distribution of low temperature fluid under different loop conditions. Related analysis to the computation is also delivered.
