Experimental Study on Cooling of Flush Mounted Ribbons into Rectangular Channel by EHD Active Enhancement Method

In the present study, the heat transfer enhancement on flush mounted ribbons established on the floor of a rectangular duct was investigated. These flush mounted ribbons were used as heat sources and means of cooling of them has been carried out with air flow by experimental procedure. The flow was two dimensional, steady, viscous and incompressible with regimes of either laminar ( 500 £ Re < 2000 Dh ) and turbulent ( 2000 £ Re £ 4500 Dh ). The hydrodynamics and heat transfer behavior of this flow was studied by active method with application of corona wind. The state of the art of this work is its experimental investigation of an EHD1 active method and enhancement of heat transfer from surfaces of flush mounted ribbons. For conducting the experiment, a special apparatus has been designed. The comparison of the results for various boundary conditions of problem was fairly agreement
