An impinging jet in a dielectric liquid is generated by applying a high potential difference to a blade-plane geometry. This kind of jet is both a fluid flow and an electrical phenomenon. In our study, an overview of the flow field is easily obtained by using the classical particle velocity method. Two patterns of electrohydrodynamic velocity profiles of the jet can be observed when the applied high voltage varies. A typical method for a classical impinging jet is used in order to point out the specific characteristics of electrohydrodynamic jets. Electric current measurements and particle-image-velocimetry investigations are conducted synchronously, which contribute to the analysis of this electrohydrodynamic phenomenon. Two electrical current regimes are presented according to the potential difference.
