摘　　要：报道了作者近年来在低压汽轮机内湿蒸汽两相流测量技术方面的进展。由于湿蒸汽两相流中的 1次水滴、2次水滴和流场密切相关 ,作者研制了能同时测量 1次水滴、2次水滴和流场所有参数的集成化探针 ,并在 35 0MW和 2 0 0MW汽轮机上作了实测 ,得到了 1次水滴的尺寸和浓度 ,2次水滴的尺寸、速度和流动方向 。This paper reports the progress made by authors in the measurement technology for wet steam two phase flow in LP turbine. Due to the close correlation among the primary droplet, secondary droplet and flow field, a new integrated probe was developed for measuring all the parameters of droplets and flow field at same time. The measurements with this probe were carried out in 350MW and 200MW turbines, respectively.
