| 摘 要： | 应用前向散射激光粒子成像测速法，测量了油滴群在水中的浮升速度。测试表明液滴群的浮升速度同单液滴有显著不同。应用片光束的侧向散射激光粒子成像测速法，测量了液滴群在流动液体中的速度分布，并观察到高浓度的速度扰动。

VELOCITY MEASUREMENT OF THE DROPLET SWARM BY PARTICLE IMAGE VELOCIMETRY |
| |
| Abstract: | he rising velocities of oil drop swarm in stagnant water are measured by using the forward scat-tering laser particle image velocimetry (LPIV).The average velocity of droplet swarm is muchdiffrent from that of a single drop. The droplet swarm velocity profiles in flowing fluid are measuredby the LPIV with slice light beam technique.Disturbed flow of droplet swarm iS observed at high con-centration of dispersed phase. |
