高强电场中液滴的破碎

Droplet Rupture under High-Intensity Electric Fields

对高强电场中液滴的破碎进行了研究。提出了置于电介质连续相中的导电液滴在静电场中的受力模型，并通过实验对高强交变电场中影响液滴破碎的诸因素进行了研究。获得了诸因素在一定范围内对液滴破碎影响的规律，同时证明了静电场中液滴受力模型的合理性。

This paper deals with the droplet rupture under high-intensity electric fields. It is one of the fundamental study on electric field driven extraction. A force balance model on a conductive droplet suspended in dielectric continuous phase under steady electrical fields was put forward, and the factors influencing droplet rupture was studied experimentally. It is revealed that the factors, such as two phases interfacial tension of extraction system , permittivity of continuous phase, initial diameter of droplet, frequency and shape of the wave of power source etc., are all influenced on the behaviour of droplet rupture. A theoretical relationships dealing with the initiation of rupture of droplet was obtained, and the experiment results fits the theoretical results well.
