This paper deals with two-dimensional EHD flow occurring between a blade and a plate electrode a distance H apart. This type of EHD flow, known as electrohydrodynamic plumes, arises when sharp metallic contours submerged in non conducting liquids support high electrostatic potential resulting in charge injection. The aim of this paper is to analyze, from a numerical point of view, the evolution of velocity profiles, flow pattern and other relevant parameters characterizing plumes flows. Numerical results are compared with those obtained from experimental or theoretical works found in literature and show that the numerical technique used is suitable to study EHD plumes.
