Thermo-Hydraulic Analysis of Slightly Inclined Finned Channel under Natural Convection

Abstract: The influence of slight inclination, 'α' (i.e., 10°, 15°, and 20°) of the channel comprised of shrouded vertical rectangular non-isothermal fin array has been computationally investigated. Simulations are performed to obtain the convective coefficient of heat transfer for the different dimensionless fin spacing (S * = 0.2, 0.3, 0.5), non-dimensional fin tip to shroud clearances (C * = 0.1, 0.2 and 0.3), Grashof numbers (Gr= 1.08×10 5 , 4.42×10 5 and 11.5×10 5 ), fin lengths (L= 0.25m and 0.5m) and fin heights … Show more

“…Most of these studies concern flows in vertical geometries, as in the case of electronic component cooling [ 21 ] or natural building ventilation [ 22 ]. However, there are a number of studies on natural convection in inclined channels with heated walls [ 23 , 24 ], aimed at improving the performance of rooftop solar chimneys or roof-mounted solar panels. Other authors have studied mixed convection using fins to cool the channel [ 25 ].…”
