| Abstract: | 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. |
