摘要
粒子追踪测速即PTV方法是近年来受到较多关注的一种多相流全场测试技术。本文通过文献综述总结了该方法的最新进展,涵盖了其试验装置构成、多相流图像数据的处理、粒子匹配算法的分类及特点等专题内容,着重对粒子匹配进行了讨论。最后结合工程应用实例分析了使用该方法时应注意的问题。
As a full field measurement technique in multiphase flow,Particle Tracking Velocimetry( PTV) receives wide attentions in recent years. The progresses on this method from literature review was summarized,including the experimental set-up, the processing of the image data on the multiphase flow,the classification and characteristics of the particle matching algorithms. The last topic is highlighted due to its particular importance. Finally,some notions on applying the technique are pointed out for a few specific cases.
