Effect of Couette Flow on Electroconvective Vortices

Abstract

Numerical simulation of Electroconvective vortices behavior in the presence of Couette flow between two infinitely long electrodes is investigated. The two-relaxation-time Lattice Boltzmann Method with fast Poisson solver solves for the spatiotemporal distribution of flow field, electric field, and charge density. Couette cross-flow is applied to the solutions after the electroconvective vortices are established. Increasing cross-flow velocity deforms the vortices and eventually suppresses them when threshold values of shear stress are reached.
