Abstract

This study presents theoretical results on natural convection in vertical air-filled enclosures with isothermal hot and cold walls. The flow is considered to be two-dimension al laminar, und steady. The effect of the aspect ratio on the heat transfer and the natural convection flow is discussed. The effect of some finite difference schemes on the numerical method used has been discussed in this paper. The Rayleigh number varied from 103 - 106, the aspect ratio from 1-10 and the Prandtl number equals 0.73. A comparison has been also made with the available data in the literature.
