摘要
设计和发展一种扩展的测量爆炸水雾场水雾粒径的DPIV方法,并详细论述了该方法的测试原理和实验装置,同时用图像处理程序对用该测试方法得到的爆炸水雾场图像进行了处理,得到了爆炸水雾场在不同距离处水雾粒子的粒径分布.实验结果表明:爆炸水雾的粒径随着距离的增加而减小,水雾粒子在运动过程中存在二次破碎现象.
Designed and developed an extended DPIV method measuring droplet size of water mist field resulting from explosion. The working principles and set-up of the extended DPIV were discussed in details. Using image processing procedure of the pictures took by the measured method were handled, and the distributions of droplets size of water mist field resulting from explosion were got in different distances. The experimental results show that the droplet size of water mist field resulting from explosion decreases with larger of the distance of measurement, the second breakup of droplets of water mist happened in the kinetic process in air.
