Significance of Joule Heating and Fourier Heat Flux on the Dynamics of Ternary Hybrid Nanofluid Rotating in a Circular Porous Disk

This study delves into the intriguing interplay between Fourier heat flux and Joule heating, exploring their effects on a ternary hybrid nanofluid caught in the rotational dance of a circular porous disk.It unpacks the roles of Joule heating, thermal radiation, heat generation, and viscous dissipation in shaping the dynamics of heat transfer.To untangle the complex behaviour of the system, we transformed the governing partial differential equations (PDEs) into ordinary differential equations (ODEs), paving the way for a clearer insight into the physical phenomena at play.We employed a numerical solution approach, showcasing the precision of the shooting method against established techniques in the field.Our results unveil a fascinating narrative: increased thermal radiation, heat generation, and viscous dissipation significantly enhance heat transfer efficiency, thickening the thermal boundary layer in the process.On the other hand, as the magnetic parameter increases, it restricts the flow of the electrically conducting fluid, which ultimately results in a decrease in the thickness of the momentum boundary layer.This interplay of forces reveals the delicate balance governing heat dynamics in this unique system.
