The wake vortices of an impinging jet in crossflow were studied experimentally by means of laser-induced fluorescence (LIF) flow visualization and particle image velocimetry (PIV) measurement.
本文采用LIF(激光诱导荧光)流动显示和PIV(粒子图像速度场仪)测量对横流冲击射流的尾迹涡结构进行了实验研究。
The LIF technique is used for the visualization of the flow patterns which are recorded by a CCD camera at the speed of 25 frames per second.
采用激光诱导荧光技术显示流场。以每秒25帧的CCD摄象机记录近壁流动结构。
