摘　　要：应用图像处理技术对流场内汽蚀现象进行分析 ,结果表明 :应用图像处理技术可以精确地对流场内汽蚀现象进行清晰化处理及特征提取。因此 。In this paper, a new method called image manipulation, was initially introduced to analyze the cavitation of flow field. As the complexity of the cavitation development only the method of image manipulation can calculate the strength of the cavitation more accurately. Firstly this method was used to eliminate the noise, then the area of the cavitation was deduced to serve as the strength of cavitation. At last, the method was applied in an example of inducer rotating cavitation. The results showed that using image manipulation could get accurate date of cavitation easily, and the reason of the inducer shaft vibration was found out.
