摘要
介绍了利用激光多普勒测速（ＬＤＡ）技术对旋流式板塔内气液（固）两相流速度场的测试方法，给出了板塔内气体与液滴的真实流动状况．测试结果表示，在研究此类流场时，ＬＤＡ有其他测试仪器无法比拟的优点．
Laser doppler anemometry (LDA) is an non contact optical measurement technique for the velocity field of fluid flow.In this paper, the volicity field of two phase (gas liquid) in the rotating stream tray (RST) was investigated by LDA.The true flow structure of the gas and liquid in interior of RST was acquired.The results show that LDA offer uniqne aedvantages in comparision with other fluid flow instrumetations.
