Electrohydrodynamically induced flow direction in a wire-non-parallel plate electrode corona discharge

An experimental investigation has been conducted to study the net flow direction induced by electrohydrodynamic forces in a wire-non-parallel plate electrode corona discharge. The experiments were conducted at two different locations of corona wire electrode for negative and positive applied voltage from 0 to 14 kV at atmospheric pressure and room temperature, where air was used as the working fluid. It was experimentally revealed that the net flow direction of electrohydrodynamically induced gas flow in a wire-non-parallel plate electrode system was changed depending on the location of the corona wire electrode relative to the grounded electrode position.
