Opis

Numerical investigation on natural convection heat transfer has been carried out inside Isosceles triangular cavity. Finite volume method has been employed to solve momentum and energy equation. The problem is solved for various Rayleigh number, Ra and inclination angle, th. The effects of governing parameters, namely, Rayleigh number, angle of inclination th and number of chips on the streamlines and isotherm as well as average Nusselt number are considered. Enhancement of heat transfer is observed as we decrease the angle of inclination for all Rayleigh number and with the increase in number of chips we find that there is an increase in heat transfer. It has been observed that, the dominance of viscous force or buoyancy force is playing a significant role to characterize the heat transfer rate. The results show that heat transfer coefficient decreases in a geometry with chip as we decrease the angle of inclination th up to a certain value of th and then increases as we further decrease the angle of inclination th.
