Abstract

A corona discharge generating device includes a housing having a bottom wall and a side wall made of conductive material adapted to be electrically connected to a negative high-voltage pulse generator. A ferrofluid layer is provided inside the housing, on the bottom wall. An insulating sheet is provided inside the housing, over the ferrofluid layer, for supporting a layer of electrolyte liquid. A discharge electrode is placed at a predetermined distance over the layer of electrolyte liquid, and adapted to be connected at a positive high-voltage. A magnet is provided for inducing a magnetic field on the ferrofluid layer, so as to form magnetically induced cones on the surface of the ferrofluid layer, in order to enhance formation of Taylor cones on the surface of the electrolyte liquid, when the negative high-voltage pulse is applied on the housing.
