Abstract
A narrow ionic wind device is investigated in this experiment, in order to aim at the application to a micro electrohydrodynamic (EHD) gas pump with a needle-ring electrode system, operating without mechanical parts. The EHD pump consists of a needle electrode attached with a tapered glass tube, where the grounded ring electrode is located on outer surface. Under AC dielectric barrier discharge condition, the ionic wind is generated inside the tapered glass tube as a micro gas pump. The distribution of ionic wind velocity under AC corona discharges is analyzed by using particle image velocimetry (PIV). Ionic wind flow rate and energy efficiency are presented as a function of the corona discharge current or the electric power. The energy efficiency of ionic wind is discussed in terms of an EHD non-dimensional analysis for the corona discharge current.
