A study of the induced flow pattern, in quiescent air,by the trielectrode plasma curtain (TPC) discharge is presentedand analyzed in terms of the electrical characteristics of thedischarge. The TPC discharge is based on the combination of a dielectricbarrier discharge (DBD) with a corona discharge (CD) in athree-electrode system, and basically, it consists of the “stretching”of a pure DBD by the action of a negative CD generated betweenthe active electrode of the dielectric barrier and a remote thirdelectrode. It was found that the observed flow pattern is mainlycontrolled by the forces exerted at the vicinities of both exposedelectrodes, where the electric field is very high. On the other hand,the net force produced at the interelectrode gap seems to be verysmall in spite of the large current flowing there, a fact that canbe attributed to the relatively low value of the electric field at thestreamer channel.
