摘要：

The question of the rheological effects of non-Newtonian fluids on the natural convection mechanism in a porous medium is addressed. These effects are illustrated for a power-law fluid with a yield stress, in which the yield stress is temperature dependent. The case of a constant-temperature boundary along a heated vertical plate embedded in a porous medium is investigated. For this case the approximate self-similar solutions in closed form of steady and transient states are presented and discussed. The rheological effects on the convection pattern are shown.
