摘要
粒子图像测速(PIV)是一种基于流场图像互相关分析的二维流场非接触式测试技术,在流场测量中占有非常重要的地位。首先介绍了PIV技术的测试原理及应用特点,阐述了其在船舶拖曳水池、柴油喷雾、气固多相流动及离心泵内部流场领域的应用状况,同时指出了PIV技术的未来发展方向。
The particle image velocimetry （ PIV）, an key method to measure the flow fluid, is a nonintrusive technique to measure the planar distribution of velocity in the fluid based the cross-correlation of flow images. In this paper, the testing theory and applying characteristic of PIV are introduced in details. The application in towing tank of ship, diesel spray, multiphase flow of gas-solid and inner flow field of centrifugal pump is described. Finally, the development direction of PIV is proposed.
