| Summary: | The research introduces a novel aspect by focusing on the examination of a Casson nanofluid flowing over a nonlinear stretching sheet within a porous medium. The primary aim of this study is to explore the heat-mass transfer phenomena in this particular scenario. Notably, the Casson fluid employed in this investigation contains nanoparticles and is subjected to the effect of a constant magnetic field (MF). Furthermore, the study takes into consideration the effects of slip in velocity, concentration, and temperature on the flow of nanofluid over a nonlinear stretching surface. The research takes into account heat generation and viscous dissipation, and it solves the descriptive equations using similarity transformations and the finite difference approach. Heat generation and viscous dissipation play a crucial role in influencing the heat transfer process. The study illustrates and examines the effects of several parameters on the profiles of velocity, concentration and temperature. For various incorporated factors indicated in the provided problem statements, the Sherwood number, Nusselt number, and skin friction coefficient are analyzed and evaluated. Temperature augmentation occurs when the heat-generating parameter is increased. Variable thermal conductivity and temperature are directly correlated, as well. Furthermore, by contrasting the acquired results with published findings in a particular limited case, the accuracy of the current technique is shown. The notable results reveal that as the magnetic number, porous parameter, and stretching parameter increase, there is a decrease in both heat-mass transfer rates.
