Generation of entropy for MHD flow of Casson fluid past a vertical cone with Dufour effect

Abstract

The purpose of this study is to examine the entropy generation for a Magnetohydrodynamic flow of a Casson fluid subject to a vertical cone. Here the impact of reaction by chemical and diffusion-thermo is scrutinized. Physical aspects of radiative flux transverse to the surface are deliberated. The governing non-linear PDEs and the expression for entropy generation are non-dimensionalized with the help of dimensionless quantities. Finite difference technique is implemented to get numerical and graphical results for the non-linear system. Bejan number for the heat transfer is also examined. The results obtained shows that entropy generation and Bejan number are strongly influence by the embedded flow parameters.
