چکیده انگلیسی
This investigation deals with entropy generation optimization and nonlinear dissipative flow of Sisko fluid due to a rotating disk. Joule heating effect is considered. Mathematical model is obtained for the present flow problem. Nonlinear systems are solved for convergent series solutions. Analysis of various flow variables on Bejan number, volumetric entropy generation rate, temperature and velocity are discussed. Present analysis depicts that irreversibility rate (entropy generation rate) and Bejan number are enhanced for radiation parameter, whereas reverse behavior is noticed for Brinkman number and material parameter. The velocity and temperature fields are increasing for larger material parameter and temperature ratio parameter. The obtained results are helpful in understanding the irreversibility (entropy generation) for flow of non-Newtonian fluids. Comparative study is made for temperature, velocity, Bejan number and entropy generation by considering shear thickening and thinning fluids. Finally, a comparison is given with the previous available results.
