Abstract:Entropy generation is a crucial aspect of fluid dynamics and happens during all flow processes. In a sense, entropy indicates how to minimise thermal energy losses. This study examines entropy generation for a magnetohydrodynamic Casson fluid flow subject to a vertical cone. Here, 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 total entropy expression are non-dimensionalized with the dimensionless quantities. ; Finite difference technique is implemented to get numerical and graphical results for the non-linear system. Entropy generation and Bejan number for the heat transfer has been analysed through plots and tables. The obtained results demonstrate that the embedded flow parameters have a considerable influence on both Bejan number and entropy generation. Bejan number with the influence of Casson parameter has a proportional effect with the Hartmann number and it falls with the rise in Dufour effect.
