摘要
本文专门介绍一种测量旋转流场的新技术。作者研制了一合旋转机械编码仪，结合应用在二维激光流速计系统，对几种水泵叶轮的内流场进行测量，获得了成功，得到了平均速度、湍流度、相关系数及雷诺应力等各力学量与相位角度之间的对应分布结果。
This papers will specially introduce one of the newest technique of measuring rotary flow. The writers have made a instrument-Rotating machinery resolver. It was used with a two dimension LDV system. The rotary flow inside of the impeller in a water pump is measured successfully. The result obtained is mean velocity and other eihgt mechanical parameters. The distribution of that within a phase angle region would be showed. This is a useful methed for someLDV users.
