An experimental study was conducted to examine the heat transfer enhancement in forced convective channel flow by means of the ionic wind induced between the plate wall and plural negative wire electrodes, which were put at the center line of the channel. A theoretical analysis was also performed on electric, flow, and temperature field taking account of the interactions among these fields. Firstly, the combined flow field where the cellular secondary motion occured owing to the field's interaction was characterized in conjunction with the bulk flow velocity and the electric field strength. Secondly, the enhancement of convective heat transfer rate was recognized, especially under low Reynolds number, and its mechanism was clarified. On the basis of these results, the heat transfer performance was shown in connection with the amount of electric power and pumping power.
