摘要
提出了一种利用粒子近前向散射光的PIV技术,可对两维流场的瞬态流速分布进行测量,且散射光强可大为提高和测量结果不受成像系统景深的限制。对两种PIV技术进行了实验比较。
A PI V technique which uses the near forward scattering light from particles was developed, which has the ability of measuring instantaneous two dimensional velosity distribution of fluid flow field, light intensity can bo increased greatly and no limitation to the measurement result by the depth of field.Experimental comparison of two PIVs techniques was made.
