摘　　要：为了研究汽轮机内湿蒸汽两相流中二次水滴的特性,本文研究了用图像法测量二次水滴的可行性,在水滴喷雾实验台上进行实验,对单帧图像进行处理,得到了运动水滴粒径、速度和流动方向角。实验分析结果表明,该方法可以测量汽轮机内二次水滴这些参数。For the purpose of studying characteristics of coarse water in steam turbine, moving water droplets images have been acquired by using the image measurement system in the water spraying experiment platform and the measurement methods of droplets size, velocity and flow angle have been studied in this article. The experimental results show that this method is suitable for coarse water measurement in steam turbine.
