摘要：
The effect of applying an electric field on natural convective heat transfer enhancement from an inclined heated plate was investigated experimentally. The effect of parameters such as applied voltage, heat flux, angle of inclination, and spacing of electrodes on heat transfer enhancement was studied. It was found that by increasing the applied voltage, increasing the angle of inclination, and decreasing electrode spacing, the enhancement ratio increases. The maximum enhancement was obtained for the bottom surface of the horizontal plate, as for this case the enhancement ratio of 4.5 was obtained by applying 175 kV voltage.
