N2 - A numerical study of laminar convection in a porous enclosure saturated with a power-law fluid was performed. Hydrodynamic and heat transfer results are reported for the configuration in which the enclosure is heated from a side wall while the horizontal walls are insulated. The flow in the porous medium was modeled using the modified Brinkman-Forchheimer-extended Darcy model for power-law fluids. Parametric studies were conducted to examine the effects of Darcy number, Rayleigh number, and power law index. The results indicate that when the power law index was decreased, the circulation within the enclosure increased leading to a higher Nusselt number and these effects were enhanced as the Darcy number was increased. As the power law index was decreased, the boundary layer regime was shifted from a higher range of Darcy number to a lower range. An increase in Rayleigh number produced similar effects as a decrease in power law index.
