Abstract
The final object of this study is to enhance the heat-exchange performance of fin-plate heat exchangers using ionic-wind generated at the surfaces of each fin. In this study, an ionic-wind generator consists of a glass plate, a discharge electrode and ground electrodes put on the glass plate. Ionic wind is generated by applying AC high voltage of 13.5 kHz with DC bias. When the peak and the DC bias voltages were 6 kV and 2.25 kV, respectively, the maximum wind velocity was 1.3 m/s at within 1.0 mm from the surfaces. The ionic wind generated vortices, resulting in a little wind of the reverse direction at the position of y-coordinate larger than 1.5 mm.
