RÉSUMÉ
In this work, computational results are compared to experimental benchmark results for natural convection in a cubical cavity, and these results are extended to two classes of non-Newtonian fluids: Powell-Eyring and extended Williamson. Good agreement is seen between the experimental and computational results for most of the Newtonian cases. The non-Newtonian results show increased heat flux with increasing non-linearity of the models. The non-Newtonian cases for the diagonally inclined orientation also show periodic behavior not seen in the Newtonian cases.
