摘要

In the present study, the heat transfer enhancement on ribs established on the floor of a rectangular duct was investigated. These ribs 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≤ReDh<2000) and turbulent (2000≤ReDh≤4500). The hydrodynamics and heat transfer behavior of this flow was studied by passive, active and compound methods with application of corona wind. The state of the art of this work is its experimental investigations of a compound method including EHD. 1Electrohydrodynamics. ~1 active method and passive method of perforated surface between ribs and enhancement of heat transfer from their surfaces. For conducting the experiment, a special apparatus has been designed. The comparison of the results for various boundary conditions of problem was fairly agreement.
