On the motion and deformation of two fluid particles in an electric field

Abstract

The steady creepind flows, produced by an electric field, it and around two fluid particles are considered. The flows are assumed to be axisymmetric and fluids are considered to be Newtonian, incompressible, and possessing constant, though different viscosities. Semianalytical solutions for both the electric and the flow fields in and around the fluid particles are obtained. Further, small deformations of the two fluid particles are calculated. At the same time the motion and deformation of a compound droplet produced by an electric field are determined.
