Abstract
Two-dimensional numerical simulations have been conducted to investigate the heat transfer in a square cavity where a heat source of a constant and uniform temperature is on the middle of a vertical side wall, the other side wall is kept isothermal at a temperature lower than that of the heat source and the rest of the wall is adiabatic and an adiabatic object is located inside. It has been found that in the cases where the flow pattern between the heat source and the object resembles the one in the channel between two parallel plates, the heat transfer characteristics are well correlated by using modified Nusselt and Grashof numbers proposed in this study.
