Abstract :
The results of numerical calculation on the relationship between AC electrical conduction and EHD motion in mineral oil are presented. The distribution of two dimensional flow velocity, current density, and tan δ under 50 Hz stress are calculated. It is found that the motion is able to induce by Coulomb´s forces acting the positive charge existing in the electrical double layer.
