Abstract
This study explores the effects of heat transfer on the Williamson fluid over a porous exponentially stretching surface The boundary layer equations of the Williamson fluid model for two dimensional flow with heat transfer are presented Two cases of heat transfer are considered ie the prescribed exponential order surface temperature PEST case and the prescribed exponential order heat flux PEHF case The highly nonlinear partial differential equations are simplified with suitable similar and nonsimilar variables and finally are solved analytically with the help of the optimal homotopy analysis method OHAM The optimal convergence control parameters are obtained and the physical features of the flow parameters are analyzed through graphs and tables The skin friction and wall temperature gradient are calculated
