Solar Energy Utilization of Radiative Implication of Trihybrid Xue‐Modeled Nanofluid Flow for Oblique Stagnation Point Flows

This study uses the Xue model to explore how well a nanofluid transfers heat in a steady oblique stagnation‐point flow. It examines the impact of nonlinear thermal radiation on a mixture of three different nanoparticles as the fluid moves along a stretching surface. This intended comparison model is unique and still scarce in the literature. Trihybrid nanofluids or composites have, therefore, been created to enhance heat transfer efficiency. Three different types of nanoparticles (Fe3O4, Cu, and TiO2) are exploring circumstances where ethylene glycol is the base medium. A mathematical framework is developed. Using the appropriate transformations, the system of partial differential equations (PDEs) is transformed into an ordinary differential system of three equations (ODEs), which is evaluated numerically using the bvp4c method. This integrated technique facilitates the convergence process effectively. A detailed analysis is conducted of the graphical representation and the physical behavior of important factors. On temperature and velocity profiles, the impacts of several variables, including a thermal radiation, surface heating parameter, stretching ratio, and particle volume fraction, are investigated thoroughly. The results show that the (Fe3O4 + Cu + TiO2)/ethylene glycol nanofluid outperforms with a high particle volume fraction of TiO2. It has been demonstrated that (Fe3O4 + Cu + TiO2)/ethylene glycol nanofluid with a high particle volume fraction of TiO2 has considerably greater thermal radiation than other nanoparticles.The inclusion of nanofluids significantly improves heat transfer compared with conventional fluids due to their higher thermal conductivity, which is crucial for enhancing heat dissipation at stagnation points in solar systems.
