Electric field or plasma assisted combustion has been studied to improve such combustion characteristics as flame speed, flame stabilization, and pollutant emission. In case of electric field assisted combustion, lower power consumption and less flow disturbance could be expected as compared to plasma-assisted combustion. To improve the stabilization characteristics of jet flames, the effects of AC and DC electric fields on the stabilization of jet flames have been investigated, including the influences on liftoff, blowoff, and reattachment for nonpremixed jet flames and on the liftoff of premixed bunsen flames. These findings will be discussed to identify the effect of ionic wind.
