【摘要】 PIV(粒子图像测速)技术在拖曳水池中的应用面临诸多困难。与水池岸基式PIV相比,随车式PIV具有设置灵活、连续采集的优点。本文介绍了中国船舶科学研究中心(CSSRC)拖曳水池随车式PIV技术的特点与功能及其发展阶段。介绍该系统的三个应用:高速水面船模支架周围流动观测;全附体下带与不带前置导叶、螺旋桨的水下回转体模型尾部区域流场测量;及两种不同艉附体与主体连接形式的水下回转体尾部流场的测量。展示了该系统的发展水平,及其在船舶流场研究中的作用与应用前景。更多还原

【Abstract】 There are many difficulties for PIV technique application in towing tank. The paper introduces the development progress of PIV technique application in towing tank at CSSRC. Compared with the stationary PIV, the towing PIV makes optimal use of costly experimental time, as it gives up to much more measurement time per tow. Its application in the investigation on ship flow field is also present, which indicates its bright application prospect in the investigation on naval hydrodynamics.更多还原
