In the interface of gas and dielectric liquid phases, while the phenomenon in this research aiming at analysis and an elucidation generated weak electric discharge in the gaseous phase, it was one electrohydrodynamic(EHD) phenomenon in which a liquid flowed. In the experiment, the convenience technology of the particle image velocimetry(PIV) was applied to the molecular tagging velocimetry(MTV). While developing the flow velocity measurement technology of the EHD ionic flow field of gas-liquid two-phase fluid, a quantity of amounts of electric charges and drift speed of the charged particle were turned, and the knowledge about electrical conductivity effect was acquired.
