Abstract
Purpose The purpose of this study is to analyze the entropy generation in magnetohydrodynamics stagnation point mixed convection flow of Carreau nanofluid through porous medium. Design/methodology/approach The system is solved using the homotopy scheme. Findings Minimizing radiation, magnetic, permeability and temperature difference parameters responds to minimizing entropy production. Originality/value To the best of the authors' knowledge, no such analysis has yet been reported.
