| 摘 要： | 本文根据管内沸腾汽液两相流动沿程“流型”不断变化的特点,提出用移动式电导探针对沿全流程的“流型”进行测量,实验结果证明这种方法是可行的,且与计算结果相当吻合。并整理得出环状流起始点计算的经验公式。此方法可用于其他管内汽液两相流动的“流型”测量。

| Abstract: | A new method which uses a moving conducting probe to detect the whole flow path's flow pattern that varies along a vertical round tube through which the boiling water-vapor two-phase flow is flowing and to find out the empirical formula that further estimates the beginning point of the annular flow has been proposed in this paper and been proved effective by the test results which tally with that calculated fund-mentally. This new method, of course, may be applicable to measuring the other similar situations in which gas-liquied two-phase flow exists. |
