ShareSummary
Steady natural convection of air in a two-dimensional enclosure isothermally heated from one side and cooled from the ceiling is analyzed numerically using a stream function-vorticity formulation. The effect of Rayleigh number on heat transfer is found to be more significant when the enclosure is shallow, and the influence of aspect ratio is stronger when the enclosure is tall and the Rayleigh number is high.
