Entropy optimization and Sisko material flow with nonlinear radiative heat flux and heat source/sink
The present article illustrates the salient features of entropy optimization for flow of Sisko fluid. Fluid motion in this problem is due to rotating stretchable disk. The fluid properties are discussed in the presence of nonlinear mixed convection, Brownian motion and viscous dissipation. Entropy generation is calculated and analyzed graphically. Heat transfer is analyzed for nonlinear thermal radiation, thermophoresis parameter and heat source/sink. These governing equations are tackled for convergent series solutions. Results are shown graphically. Comparison has been made with the existing literature in the limiting cases.
