Краткое описание

In the present work, a square enclosure with two ventilation ports in the presence of adiabatic differently shaped fins placed on the bottom wall of the cavity are numerically analyzed for the mixed convection case in the range of Richardson numbers from 1 to 120 at the Reynolds number equal to 300. The walls of the cavity are kept at a constant temperature, and two different fin shapes (a rectangular and a triangular one) are considered. The effect of the fin height and Richardson number on the heat transfer and fluid flow characteristics is analyzed numerically. The results are presented in terms of streamlines, isotherm plots and averaged Nusselt number plots. It is observed that the length of a fin has a considerable effect on the thermal performance of the system. The shape of a fin affects the flow field and heat transfer characteristics only at a short fin length.
