Краткое описание

In this paper, we have investigated the influence of thermal radiation, magnetic field, wall suction/injection, and porous media permeability on inherent irreversibility in magnetohydrodynamic (MHD) forced convective flow of an electrically conducting Casson fluid in a horizontal microchannel with boundary slip and saturated with porous medium. The nonlinear model problem is tackled numerically using fourth−fifth order Runge−Kutta−Fehlberg method and the computed results for velocity and temperature fields are utilized to determine the skin friction, Nusselt number, entropy generation rate, and Bejan number. Pertinent results are displayed graphically and the physical aspects are discussed. It is observed that the impact of magnetic field and Casson fluid parameter have significant effect on the entropy generation rate.
