Current density distribution on gas-liquid two-phase fluid flow in an air-wave type EHD pump

Abstract

For gas-liquid two-phase flow systems of an air-wave type EHD pump, an influence of gas-liquid interface on current conduction was investigated in this experiment. The current density distribution along EHD induced liquid flow was obtained by using a plate electrode divided into 20 channels. The maximum current density appeared at a gas-liquid interface bounded to the plate electrode. It was effectively related as an interfacial liquid flow motion based on the current conduction.
