In this work, the effect of applying an electric field on droplet formation in a T-junction microfluidic device is examined by simulations based on a recent technique known as lattice Boltzmann method (LBM). The electric field is applied in the main channel just beyond the confluence of the continuous and dispersed phases. A combined electrohydrodynamics-multiphase model that can simulate the f...

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...

Microscale fluidic manipulation 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 subject to a temperature gradient. These ions are moved as the traveling wave propagates, resulting in a drag force being exerted on t...

In this work, the nonlinear boundary value problem in electrohydrodynamics flow of a fluid in an ion-drag configuration in a circular cylindrical conduit is studied numerically. An effective collocation method, which is based on orthonormal Bernstein polynomials is employed to simulate the solution of this model. Some properties of orthonormal Bernstein polynomials are introduced and utilized t...

A weakly conducting liquid droplet immersed in another leaky dielectric can exhibit rich dynamical behaviors under the effect of an applied electric field. Depending on material properties and field strength, nonlinear coupling interfacial charge transport fluid flow trigger electrohydrodynamic instabilities that lead to shape deformations complex dynamics. We present a spectral boundary integr...
