Impact of entropy generation on hydromagnetic

Abstract

Recently and over the years, the industrial applications of second law analysis is becoming famous. Hence, this work intend to address the combined impacts of water-based nanofluids, convective boundary state, thermal radiation, magnetic field and second law of thermodynamics .The governing equations that unravel the flow within the boundary layer are provided. The transformed governing equations are obtained by guided similarity variables, the transformed equations are solved analytically by method of undetermined coefficient. Entropy generation rate and Bejan number in dimensionless form are obtained by deriving an expression through the analytical solutions of temperature and velocity. The emerging parameters of the flow are: Bejan number, Biot number, radiation parameter, entropy generation rate, skin friction, Hartman number, suction, Prandtl, Nusselt and Reynolds number. Also, the effects of these parameters are presented in graphs and tables. In addition, Entropy generation are enhanced by Eckert number, radiation parameter, permeability parameter, suction , prandtl number and Brinkman number for both copper and alumina water. Finally, the results of this work is compared with published work in the literature, this result is in consonant with this work.
