H. Aryafar, H. P. Kavehpour
TL;DR
This paper presents visual evidence of electro-coalescence where a glycerol droplet in silicone oil breaks apart under a high electric field, illustrating the fluid dynamics involved.
Contribution
It provides experimental visualization of droplet breakup due to electric stresses in a viscous medium, highlighting the electro-coalescence process.
Findings
Electric stresses cause droplet breakup at the apex.
High electric fields induce fluid deformation and rupture.
Visualizations demonstrate the dynamics of electro-coalescence.
Abstract
Electro-coalescence is the application of an electric field onto coalescing fluid bodies. The following fluid dynamics videos show a droplet coalescing into a fluid bath while embedded into a viscous medium and subject to a very high electric field. The concentration of electric stresses at the apex of the droplet cause it to break apart. The droplet is glycerol and the viscous medium is silicone oil.
