喷雾过程的相干影象法研究

An Experimental Investigation on Spray Processes Using Coherent Imaging Method for Particle Sizing

本文采用相干影象测粒法对喷雾诸过程进行了实验研究。文中简述了相干影象测粒法记录光路的特点和测量原理。本文用这种测雾技术检测了实际喷雾场的液滴尺寸和分布,对喷雾液滴与固体壁面的碰撞过程进行了直观显示与研究。最后利用双脉冲激光技术检测了喷雾液滴的速度场。这是一种结果直观,使用极其方便的测速方法。

An experimental investigation on spray processes was taken using coherent imaging method for particle sizing. The principle of the method and features of its optical system were described. The sizes and distribution of spray droplets were determined, the impingement of droplets on the wall was visualized and investigated. Moreover, the velocity field of droplets was measured by a double pulsed laser technique.
