对比分析了非静电雾滴（喷液为自来水）、静电雾滴（喷液为自来水、质量分数为2％的氯化钠溶液）在靶标周围的运动轨迹。为了获得清晰的雾滴运动轨迹图像，采用高速图像采集系统对静电雾滴运动轨迹图像进行采集，然后采用图像处理技术和LK金字塔光流法研究静电雾滴的运动轨迹。试验结果表明，静电喷雾能够改变雾滴的运动方向，使雾滴向靶标反面运动；增大喷液的电导率能够明显增大静电雾滴的“环绕”效应。

Comparisons between the trajectories of non-charged droplets ( the spray is tap water ) and the trajectories of charged droplets ( the spray are tap water and sodium chloride solution whose mass fraction is 2%) around targets had been done.In order to get the clear image of droplets ’ trajectories, a high-speed image acquisition system was used to acquire the image of droplets ’ trajectories , then using image processing technology and LK pyramid optical flow method to research the droplets ’ trajectories .The results showed that electrostatic spraying can change the movement direction of droplets, make droplets move to the back side of targets .Increase the electrical conductivity of spray can enhance the“wrap-around” effect of charged droplets obviously .
