| 摘 要： | 为了研究管排承受横向气液两相流动时的振动特性,需要测定两相流动中的空洞率分布以及空洞平均值径等参数.本文对空洞率的测试方法进行了讨论,简要地说明了光探测器的工作原理,介绍了在两相流动振动试验装置(DIVA)上用光探测器测量空气—水两相流动中局部空洞率的工作.对于测量信号,用微型数字计算机进行了处理,并对得到的结果作了分析.

| Abstract: | The distribution of void fraction and mean bubble size in two-phase flow must be measuaed in order to study the characteristics of tube row vibrations subjecteted to two-phase cross flow.This paper discusses the measuring methods of the void fraction,states the principle of optical detecton in brief and present the work of measuring local void fraction by optical probe on the DIVA test section.The signals measured are handled by a digital microprocessor and the re sults obtained are analyzed. |
