Exploring radiative and viscous dissipation effects on magnetized hybrid nanofluid (SiO2-TiO2/Ethylene glycol) for thermal performance enhancement

Abstract

The effective thermal management of various engineering processes an energy applications identify the importance of advanced thermal fluids. This investigation aims to present the improve thermal results subject to magnetized flow of viscoelastic hybrid nanofluid, incorporating the decussations of titanium dioxide (TiO₂) and silicon dioxide (SiO₂) nanoparticles due to stretched porous surface. The ethylene glycol (C₂H₆O₂) is used for base fluid. The study includes the novel thermal features like thermal radiation, internal heat generation and viscous dissipation. Furthermore, suction effects are also contributed to analyze the problem. The extension in energy equation is suggested by attributing the Cattaneo-Christov (CC) heat flux law. The problem is expressed in dimensionless form for which shooting scheme is implemented for solution task. Comparative thermal measurements are performed between the mono nanomaterials (SiO₂/C₂H₆O₂) and hybrid nanofluid (SiO₂-TiO2/C₂H₆O₂), highlighting the improved thermal capabilities of hybrid system with magnetized constraints. The simulated results convey impressive improvement in the heat transfer rates subject to hybrid nanofluid as compared to mono-nanofluid, particularly in presence of peak magnetic intensities and porous media configurations. The heat transfer enhances due to Eckert number and suction parameter. The claimed observations contribute to the improvement of next generation tailored for significance in the advanced cooling processes, industrial heat exchangers and energy systems.
