Abstract

Paper presented at the 5th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, South Africa, 1-4 July, 2007.
The paper deals with porous cavities with impermeable boundaries. Four squared isothermal bodies are located at the corners of the cavity. Adequate numerical methods, finite difference and Gauss-Siedel iterative methods were used to solve the governing equations. The analysis of natural convection heat transfer was meant for Modified Rayleigh Number, Aspect Ratio, and Nusselt Number. In the findings, the Nusselt Number emerged as a strong function of Rayleigh Number and Aspect Ratio.
