摘要
三维 LDV(Laser Doppler Velocimeter)系统基于多普勒频移和多普勒相位差原理,可以用于流动速度测量.本文阐述LDV流动速度测量技术,并对超细水雾流场进行了三维速度测量,得到了合理的实验结果.
The LDV (Laser Doppler Velocimetry) system can be used to measure the flow field velocity according to the Doppler frequency shift and the Doppler phase shift theory. The measuring technology of the flow field by the LDV was explained. The 3D flow field velocity of the water mist was studied and the reasonable results was obtained from the simulated experiments.
