Abstract.

A numerical approach is adopted to explore the entropy analysis for combined convective radiated nonlinear power law fluid over an exponentially stretched plate. Both cases of shear thinning and shear thickening are presented. The physical problem gains more significance in the presence of slip and magnetic effects. Influences of related parameters are carried out by Runge-Kutta-Fehlberg method. The results show that both the momentum and thermal boundary layer thickness shrinks faster for shear thickening case. Entropy of the system augments with generalized Prandtl number. Reynolds number is responsible for lower Bejan number. Also, an augmentation of power-law index drops entropy generation.
