摘      要：We investigate the effects of magnetic field on the entropy generation during fluid flow and heat transfer due to the radially stretching *** partial differential equations governing the flow and heat transfer phenomenon are transformed into nonlinear ordinary differential equations by using suitable similarity *** equations are then solved by the homotopy analysis method and the shooting *** effects of the magnetic field parameter M and the Prandtl number Pr on velocity and the temperature profiles are ***,influence of the magnetic field parameter M and the group parameter Br/Ω on the local entropy generation number Ns as well as the Bejan number Be are *** is observed that the magnetic field is a strong source of entropy production in the considered problem.
