Enhanced thermal transport in porous-assisted thin film flow of tri-hybrid nanofluid with viscous dissipation: Implications for energy and cooling systems

The tri hybrid nanofluid are advanced class of hybrid nanofluids presenting of combination of three distinct types of nanoparticles, comprising important applications in advanced energy systems, cooling processes, chemical systems etc. This innovative investigation aims to discuss the thermal behaviour of tri hybrid nanofluid dispersed in water base fluid subject to of unsteady thin film flow. Three types of nanoparticles including silver (Ag) , gold (Au) , and aluminium oxide (Al 2 O 3 ) are used to predicts the heat transfer analysis. The flow is subject to porous medium and magnetic force effects. Thermal investigation proceeded the significance of viscous dissipation, external heat source and radiated influence. The results quantify comparative thermal aspects for mono nanofluid (MNF), Hybrid nanofluid (HNF) and tri hybrid nanofluid (THNF). Dimensionless analysis is followed to capture dimensionless form of governing equations. Runge-Kutta-Fehlberg is implemented to facilitates numerical integration of problem. It is noted that a decrement in velocity change is observed for porosity parameter and unsteady flow parameter. The investigation further predicts that interaction of tri nanoparticles is more effective to enhance the heat transfer characteristics. Predicted computations involves significant impact on thermal management systems, cooling processes, geothermal energy extraction, solar systems etc.
