| 摘 要： | 依据“分离流线影响区域”理论对两相流在Ｔ型和Ｙ型分叉管中的相分离现象进行数值模拟,参照国外发表的实验结果,进行了数值对比,总的结果表明较为理想。同时通过计算发现分叉管的分叉角度对两相流的相分离程度有着一定的影响,并作了相应的分析。另外还对入口参数Ｘ１对相分离效果的影响进行了计算和分析。

| Abstract: | A computational program is proposed to calculate the two-phase flow in the T type and Y type branch by using a mechanistic model based on the idea that the gas and liquid flows being ex- tracted into the side branch come from the "influent zones" bounded by "dividing streamline" . A number of numerical calculations are carried out to give predictive results in good agreement with others' experiment work on this field. The calculation shows that the branch angle is one of the main factors effecting the phase separation in branch type systems. Meanwhile the influences of inlet parameter X1 are also discussed. |
