As a part of a study of electrocoalescence of water droplets in oil, the electrically induced deformations of water-oil interfaces are studied. Cases of large deformations of the interfaces involve the strong coupling of hydrodynamics and electrostatics, in which cases numerical simulation is needed. The paper presents different numerical simulations performed using the commercial software COMS...

Abstract

(1) Introduction.-The electromagnetodynamics of fluids combines the dynamics of fluids and electromagnetic theory. It has been independently developed in two theories: magnetohydrodynamics and electrohydrodynamics, depending upon the properties of the fluid considered and the prevalence of either magnetic fields or electric fields. The space permitted here forbids us from going into any apprais...

Microscale fluid flow using traveling-wave induction electrohydrodynamics is demonstrated. A three-phase traveling-wave device fabricated for the experiments provides a temporally and spatially varying electric field which helps induce ions in a fluid that is subjected to a temperature gradient. These ions are moved as the traveling wave propagates, resulting in a drag force being exerted on th...
