汽轮机内湿蒸汽两相流中一次、二次水滴的参数和流场是密切相关的，但国内外迄今没有能同时测量这些参数的技术和设备。作者成功研制了能同时测量湿蒸汽两相流中一次、二次水滴和流场的集成化探针。该探针已在３５０ＭＷ汽轮机上进行了实测。本文介绍了该测量系统的原理和构成。 However, the parameters of the secondary droplet and the flow field are closely related to each other. However, there is no technique or equipment capable of simultaneously measuring these parameters at home and abroad. The author has successfully developed an integrated probe that can simultaneously measure the primary and secondary water droplets and the flow field in a wet steam two-phase flow. The probe has been measured on a 350 MW turbine. This article describes the principle and composition of the measurement system.
