Abstract |
|
|
| In this study, we investigate the impact of non-uniform heat generation on the flow of magnetized Casson-Williamson nanofluid towards a dissipative stagnation point. The research framework incorporates chemical reaction and convective heat transfer into a mathematical model and transformed the governing partial differential equations into nonlinear ordinary differential equations through similarity variables. These equations were solved using fourth-order Range-Kutta method in conjunction with the Newton-Raphson shooting technique. The results for the Nusselt number of the current model were juxtaposed with available work in literature and excellent agreement had been established. The results revealed that the magnetic field parameter significantly influenced the velocity, temperature, and concentration profiles, with Casson nanofluid showing enhanced thermal properties while Williamson nanofluid excelling in mass transfer efficiency. This indicates that Casson nanofluid is a superior fluid for enhancing thermal systems like heat exchangers, While Williamson nanofluid is suitable for processes requiring efficient mass transfer, such as industrial mixing. These insights contribute to the design of advanced biomedical, energy management and cooling devices. |
