摘要

为了研究高压静电场中雾滴的微观动力学过程

利用高速相机观察雾滴在无动力空腔电极雾化装置中的运动状态

并分析了电压和粒径对雾滴加速度、速度、运动轨迹和雾化半角的影响。结果表明:雾化电压对雾滴粒径的分布有影响

电压越高大粒径雾滴出现的概率越大;雾化电压和雾滴粒径对雾化半角和雾滴在电场中的运动轨迹有影响;雾化电压和雾滴粒径对雾滴在电场中运动时的加速度有影响

且加速度与电场强度的平方成正比

与雾滴粒径成反比;雾滴远离电极尖端的过程中

电场强度迅速衰减

雾滴所受电场力迅速减小

雾滴在电场中做变加速运动

并且距离电极尖端10 mm时

其加速度趋于0。

Abstract

In order to study the microcosmic dynamics process of droplets in high-voltage electrostatic field

we observed the motion state of droplets in the non power cavity electrode device by using a high-speed camera. We also analyzed the effects of voltage and particle size on acceleration

movement trajectories

and the expanding angle of atomization. The results show that the voltage will affect the droplet diameter distribution. The higher the voltage is

the greater the probability of large droplet is. The atomizing voltage and droplet diameter will affect the atomizing semi-angle and the trajectory of droplets in the electric field. The atomizing voltage and the droplet diameter will affect the acceleration of the droplet in the electric field. The acceleration is proportional to the square of the electric field intensity and inversely proportional to the droplet diameter. During the process of the droplet getting far away from electrode tip

the electric field intensity decays rapidly

the electric field force of the droplets decreases rapidly

and the droplets accelerate in the electric field. And when the distance between the droplet and the electrode tip is longer than 10 mm

the acceleration tends to 0.
