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.
