Abstract
|
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 ≤ ReDh ≤ 2000) and turbulent (2000 ≤ ReDh 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.
