Abstract

Two dimensional natural convection for a fluid of third grade, in an inclined cavity of arbitrary aspect ratio is solved by a regular perturbation for small Grashof numbers. Non-Newtonian effects appear at the third order of the analysis in accordance with Tanner's theorem due to the two dimensional nature of the flow. In this slow flow generated by small temperature gradients the contribution of the elastic effects to non-Newtonian behavior is much larger than the shear-thinning behavior. The viscoelastic flow field shows dramatic changes from the Newtonian field.
