In this work, an experimental investigation of non-intrusive two-phase electrohydrodynamical pump "Air-Wave Type EHD Pump" was conducted. The electrode system consisted of a wire electrode in a gas-phase and an inclined plate electrode in a gas-liquid interface. The operation of DC corona discharge electrohydrodynamically induced a liquid flow phenomenon, and the liquid was pumped along the plate electrode surface. The pumping performance was depended on a characteristic of ionic wind. The experimental analyses of electrohydrodynamically induced liquid flow in the liquid reservoir were carried out by a tracer particle image velocimetry. The results showed quantitatively velocity distributions of liquid flow inside the reservoir and the interfacial liquid flow. Current density distributions of ionic wind along the gas-liquid interface were obtained by using the plate electrode divided into 20 channels. It was related as the interfacial liquid flow motion. The liquid flow distributions were characterized with dimensionless EHD parameters. The effects of electrical current conduction on the electrohydrodynamically induced liquid flow distributions of the gas-liquid interface were discussed.
