摘要

The interaction of non-uniform heat sources and viscous dissipation effects introduces intriguing complexities in studying hybrid nanofluid dynamics over an elongating surface, a topic of significant interest for thermal engineering applications. Such phenomena hold the potential for advancing heat transfer efficiency in cutting-edge technologies like cooling systems, energy storage, and material processing, where precise thermal regulation is paramount. Thus, the current research investigates the impact of an inclined magnetic field and a non-uniform heat source on the flow dynamics of radiative EG-MoS2-SiO2, considering the impacts of Joule heating and viscous dissipation over a convectively heated elongating surface. The governing equations, representing the intricate dynamics of hybrid nanofluid stream, are formulated and solved by employing the Runge–Kutta method integrated with the Shooting technique to address missing initial conditions. Numerical outcomes are rigorously validated against established literature, showcasing remarkable alignment. Key parameters such as nanoparticle concentration, magnetic field inclination angle, non-uniform heat source intensity, Eckert number, thermal Biot number, suction velocity, and linear radiative heat flux are analyzed to elucidate their effects on flow characteristics near the stretching sheet. Graphical representations of the friction factor and local Nusselt number are provided to illustrate their dependence on these parameters. The findings reveal that magnetic field inclination and uniform suction significantly influence thermal regulation and fluid momentum. A nanoparticle concentration of 40% enhances the thermal boundary layer thickness, driven by increased thermal Biot number, viscous dissipation, and radiative heat flux near the sheet surface. The comparative analysis underscores that hybrid nanofluids display superior momentum and thermal boundary layer behavior compared to traditional nanofluids, highlighting their potential in optimizing heat transfer systems.
