Abstract

The heat transfer rates inside rectangular air closures of aspect ratios between 0.1 and 1.0 are studied numerically for a Rayleigh number ranges between 10³ and 10⁶ and Pr = 0.73. The shallow enclosures have isothermal hot and cold vertical walls. The flow is considerd to be two-dimensional, laminar and steady. The effect of the aspect ratio on the heat transfer and the natural convection flow is discussed. A comparison has been made with the available data in the literature.
