Electro Hydro Dynamic Enhancement of Heat Transfer by Different Working Fluids in a Forced

Abstract: The flow in channel occupies an important place among the several heating systems. At the same time there is a great need of maintaining and running the system effectively. There are several ways of improvement in thermal efficiency of a system, One of the ways by which we can improve thermal efficiency of the system is to take the advantage of electric field. In the present work the effect of electric field in combination with flow and temperature fields is studied experimentally in a vertical annulus, uniformly heated on the outer wall, a dielectric liquid is allowed to flow in the forced convection loop by using centrifugal pump in a channel. Sharp points are added perpendicular to the inner wire electrode and voltages are applied to it, while the outer wall is grounded. Experimental apparatus is fabricated to conduct the experiments with heat input, voltage supplied and mass flo
