Abstract: A steady laminar natural convection of air flow in a sinusoidal corrugated enclosure containing a tilted hot thin plate located symmetrically at its centreline is numerically studied. The enclosure horizontal walls are adiabatic, while the vertical walls are sinusoidal corrugated with corrugation frequencies varied from 1 to 3 and kept at cold temperature. Finite volume was used to solve governing equations. Calculations have been made for Rayleigh numbers ranging from 10³ to 10⁶ and Prandtl number was taken to be 0.71. The average Nusselt number is found to increase as Rayleigh number increases and it slightly increases with corrugation frequency.
