Control of natural convection heat transfer in enclosure using inclined plate with finite thickness

Natural convection cavities is encountered in various engineering applications, such as heating and ventilating of living spaces, fire in buildings, solar thermal collector systems, electronic cooling devices, in storage of radioactive wastes. In this study, natural convection heat transfer in a square cavity with a fin mounted on a vertical wall has been performed numerically and experimentally. Vertical boundaries are adiabatic and horizontal boundaries are isothermal. Two dimensional equations of conservation of mass, momentum and energy are solved through finite difference method. Successive Under Relaxation (SUR) method is used to solve linear algebraic equations. Results have been obtained for various geometrical parameters as the height, thickness and position of the partition and Rayleigh numbers. The partition is accepted as conductive. Obtained results are presented with streamlines, isotherms, local and mean Nusselt numbers. It was found that Rayleigh number and the fin mounted on the wall have significant effect on natural convection heat transfer and flow field.
