Abstract
Purpose
The purpose of this study is to scrutinize the effects of entropy generation and nonlinear mixed convection on the boundary layer flow of second grade fluid induced by stretching sheets. Heat transfer effects are accounted in view of viscous dissipation and nonlinear thermal radiation.
Design/methodology/approach
Optimal homotopic asymptotic method procedure is adopted to obtain the analytical solution of nonlinear ordinary differential equations.
Findings
It has been noticed that Hartmann and Brinkman number has reverse characteristics against entropy generation and Bejan number.
Originality/value
To the best of the authors’ knowledge, no such analysis has been reported to date.
