Abstracts : Rough surfaces are one of the most effective
techniques to increase heat transfer. In this study,
we have created rough surfaces in plain duct
by (e/Dh = 0.043) with changing angle of rib 450 and
600. So we have developed an experimental setup with
dimensions of the triangular duct base and height is
200mm and 350mm respectively. We had taken
different readings at a constant flow rate and
changing the temperature of the surface plate.
From experimentation, we have found Reynolds
number, Nusselt number and friction factor for three
plates (plain, 450 and 600) and found 450 angle rib to
have better results. Artificial roughness creates the
turbulence to the flow which leads to increase the heat
transfer between the air and the heated wall.
Roughness is created in such a way that it breaks the
laminar sub layer region i.e. near the wall. There is
various method to provide artificial roughness on the
absorber plate such as casting, forming, machining,
blasting, welding ribs and/or fixing thin circular wires,
etc. The easiest and cheapest way of providing artificial
roughness on the underside of the absorber plate is
sticking of ribs The scope for this study would focus all
necessary activities for benchmarking the existing
application with the current performance level and
performance standards to be set for arriving at the
objectives of the dissertation work.
