Experimental and Numerical Analysis of the Flow Induced by Electric Injection in Blade-Plane Geometry

摘要

This paper deals with two-dimensional electro-hydrodynamic plumes that arise when a sharp metallic contours submerged in non conducting liquids supports high electrostatic potential resulting in charge injection. Experiments by PIV measurements and numerical simulations have been conducted in order to confront the both approaches. A very good agreement has been found through velocity profiles and velocity field which testifies the relevance of our numerical model. Some captions of the temporal evolution of the charge density which is not accessible from experiment was given thanks to the numerical simulation.
