Abstract: | A boundary layer analysis was presented to study the non-Darcy-free convection of a power-law fluid over a non-isothermal
two-dimensional body embedded in a porous medium. The Ostwald-de Waele power-law model was used to characterize the non-Newtonian
fluid behavior. Similarity solutions were obtained with variations in surface temperature or surface heat flux. In view of
the fact that most of the non-Newtonian fluids have large Prandtl numbers, this study was directed toward such fluids. The
effects of the porous medium parameters, k
1 and k
2, body shape parameter, m, and surface thermal variations parameter, p, as well as the power-law index, n, were examined. |
