High voltage electrical discharge is a process by which a currentflows from an electrode with a high potential into a neutral fluid, by ionizing that fluid a region of plasma around the electrode is being created.HVED could be happen in partial or complete breakdown and both ofthem are used in the food industry. Several types of partial dischargesin gaseous medium have been known such as glow discharge, dielectricbarrier discharge and corona discharge but among them the corona discharge has drawn more attention in food industry than others.One of the effects of the corona discharge is the generation of anelectric field induced flows or secondary electrohydrodynamic flow(EHD), which is produced by transferring of momentum from highspeed drifting ions to surrounding air molecules
