Abstract
Experimental research was conducted to investigate basic characteristics of micro fan utilizing ionic wind in pin-to-plate gas discharge field. When high voltage was applied between the electrodes, ionic wind flowed toward heated plate through a hole of plate electrode. This research was focused on optimization of the electrode configuration by investigating the performance of the fan and the enhancement of the local heat transfer coefficients. The main conclusions were: (1) Flow rate increased with the increase of the hole diameter, and in the same hole diameter, static pressure increased with the increase of the plate thickness. (2) A gap-to-hole diameter ratio of 0.86 was found to be an optimal value that gives the highest peak power and efficiency. (3) The enhancement of the heat transfer coefficients increased with the increase of the distance between the plate electrode and the heated plate.
