Convective flow of Sisko fluid over a wedge with viscous dissipation

In this article the convective flow of Sisko fluid past a wedge under the variable free stream velocity is analyzed. Viscous dissipation effects are also taken into account. The effects of shear thinning and thickening on flow and heat transfer are analyzed in depth. The influence of the wedge angle parameter on flow and heat transfer is spanned from stagnation point down through flat plate flow to the separation point. Employing the suitable transformations the governing equations are reduced to a system of nonlinear ordinary differential equations. The resulting equations are then solved numerically by implicit difference method in the domain [0, ∞). The numerical results for the velocity and temperature fields are graphically presented and effects of the relevant parameters are discussed in detail. In addition, the displacement thickness, momentum thickness, skin-friction coefficient, and local Nusselt number for different values of the pressure gradient parameter are calculated in tabulated form. Further, the present results are also validated by comparing with the previous pertinent literature.
