Boundary layer flow of Carreau fluid over a convectively heated stretching sheet

Two-dimensional boundary layer flow of Carreau fluid past a permeable stretching sheet is studied. Heat transfer subject to convective boundary conditions is analyzed. The relevant equations are first simplified by using boundary layer assumptions and reduced to self-similar forms by appropriate transformations. The problem is governed by various interesting parameters including power-law index (n), relaxation time (^λ1), Prandtl number (Pr) and the Biot number (Bi). Series solutions are computed by homotopy analysis method (HAM). Fields are influenced appreciably with the variations of embedded parameters. Numerical values of skin friction coefficient and local Nusselt number are also tabulated.
