| 摘 要： | 突缩再突扩管道并非突缩和突扩接头的简单叠加。试验发现：当突缩、突扩接头的距离一定时，管道压力降与两相流干度和气体流量有关，文中由此得出了相应的计算式。

| Abstract: | An abrupt converging and abrupt diverging piping should not be viewed as nsimple superimposition of an abrupt verging connectioe to an abrupt diverging one.It has been found through tests that under the condition of a given tance of the abrupt convergent and abrupt divergent connection the pressure drop in a piping is realnted to the dual-phase flow dryness and as flow rate for which the authors have derived the corresponding calculation formulas. |
