Abstract

A mathematical model for three-dimensional laminar steady flow of an incompressible viscous neutrally charged carrier fluid mixed with an electrically charged fluid is presented. All magnetic fields are neglected. Thermally induced buoyancy is incorporated via Boussinesq approximation while including Joule heating effects. Numerical results demonstrate the detrimental effects of numerical dissipation on the accuracy of the solution. Bending of a stream of charged particles under the influence of an electric field and an electrohydrodynamic instability are demonstrated
