环状两相流空泡份额新析

Analysis of void fraction for annular two-phase flow

对圆管内环状两相流的空泡份额进行了分析.首先推导出气相摩擦乘子的一般表达式,然后求得空泡份额与滑速比的解析式,并进行了分析讨论.与有关文献结果的比较表明:在一定的压力范围内文中所得的解是正确、可信的.

The void fraction of annular two-phase flow inside cylinder is analyzed. The general expression of friction factor for gas phase is derived, then the new expressions of void fraction and velocity ratio of gas to liquid are given and discussed. The comparison with the results in the published lectures shows that the obtained result in this paper is accurate and credible within a certain pressure.
