Numerical study on natural convective heat transfer in a square enclosure with horizontal fins

摘要

In this study, the effects of fin spacing attached to the vertical heating wall inside an enclosure and Rayleigh number on the average Nusselt numbers were investigated through numerical analysis. The average Nusselt number increased as the Rayleigh number was increased, but was lower in case of the adiabatic fin than that the without fin. The results for the conductive fin showed the same or slightly lower values than the without fin regardless of fin spacing.
