光学探针测量汽轮机排汽的实验研究

Experimental Study on the Measurement of Turbine Ex- haust Steam Wetness with an Optical Probe

本文介绍了作者研制的湿蒸汽光学探针及其在12MW汽轮机上测量的初步实验结果.表明光学探针的研制是成功的.为测量汽轮机内效率、排汽湿度和水滴尺寸,为研究湿蒸汽两相流和叶片水蚀,提供了一种新的测量手段.

An optical probe for wet steam, developed by the authors, is presented, together with preliminary test results obtained on a 12MW steam turbine. The results show that this optical probe successfully provides a new way for measuring turbine's internal efficiency, exhaust steam wetness and water droplet sizes. It is a handy contraption useful in the research of two phase flow in wet steam and blade erosion. 5 figs, 4 tables and 13 refs.
