Abstract—Natural convection of air in an inclined square enclosure was numerically investigated. The left and right walls of the enclosure were maintained at the uniform hot and cold temperatures, respectively, while the top and bottom walls were adiabatic. The enclosure was filled with real air, a compressible Newtonian fluid. The finite volume method was employed to discretize the partial differential equations of airflow in the enclosure. The angles of the inclination of a square enclosure giving the maximum average Nusselt numbers are 110o for Ra = 1103 and 130o for 3103 Ra 1104.
