| 摘 要： | 介绍了一种新的PIV(Particle Image Velocimetry)测速技术——白光气泡图象测速技术。用电解水产生的氧泡作为流场示踪粒子,用普通闪光灯组作为PIV底片记录的多脉冲光源。其主要优点是:对实验设备无污染;不需要高能量激光光源;并可获得高信噪比的PIV底片。

| Abstract: | A new kind of Particle Image Velocimetry (PIV) ,the White Light Bubble Image Velocimetry (WLBIV) is presented. The oxygen bubble generated from electrolized water is used as the particle tracer in the flow field. A flash set is used as the multi-pulse light source for recording PIV film. With WLBIV method there are no dusty pollution on the testing facilities and no need of high-power laser. PIV film with higher signal-to noise ratio could be obtained . |
