摘　　要：本文针对用光学成像法提供划分超空化阶段流型的判据问题 ,使用激光片光源照明及抓帧速率 4 5 0 0帧 /秒的高速摄像系统 ,对流速为 10m/s的绕水翼超空化流场进行了可视化测量。通过对原始图像定量分析结果表明 。Laser sheet and high-speed camera with 4500 FPS were used to measure the supercavitation flow around a hydrofoil where average velocity of water is 10 m/s. To capture images of experimental in supercavitation flow were processed by quantitative image analysis, image segmentation, point operation. As a result, cavitation void phase in supercavitation flow around a hydrofoil was continuous.

关 键 词：超空化流动 空泡相 连续 图像分析
