Abstract :
Ionic wind of an electrohydrodynamically induced gas-liquid two-phase flow fields is experimentally measured. Since the electrohydrodynamic liquid flow motion will be created by an interrelation of ionic wind along the gas-liquid interface, new approaches are required to analyze this electrohydrodynamic gas-liquid two-phase flow type. In this work, ionic wind measurement along the stratified dielectric liquid was carried out by a particle image velocimetry where the measurement system was used to derive the flow velocity fields from time-series digital images of flow field illuminated by a light sheet for computer tomography. The visualization images of ionic wind flow patterns obtained by a smoke wire method, and the qualitative optical characterization of the ionic wind velocity fields is shown in detail. The ionic wind characteristics along the gas-liquid interface are discussed from the experimental results
