摘要：

In the present study, the heat transfer enhancement of a bundle of flush-mounted ribbons placed on the floor of a rectangular duct was investigated experimentally. The flush-mounted ribbons act as heat sources and the cooling happens with air. The air flow was 2-D, steady, viscous, and incompressible under either laminar (500 <= Re-Dh, <= 2000) and turbulent (2000 <= Re-Dh 4500) conditions. The hydrodynamics and heat transfer behavior of the air flow was studied by means of an active method with application of corona wind. The state-of-the-art of this work revolves around an experimental investigation of an electrohydrodynamics active method and heat transfer enhancement from the surfaces of the flush-mounted ribbons. Due to the intricacies of the required experiment, a special apparatus needed to be designed and constructed.
