Thermohydrodynamic Behavior of Nonlinear Slip Flow of Ternary Hybrid Nanofluid in Low and High Porosity Porous-Media: Applied to Packed Bed of Small Particles and Metal Foam

Abstract

The present study aims at exploring thermohydrodynamic behavior of nonlinear slip flow of Ag + Al2O3 + Graphene +Water ternary hybrid nanofluid (THNF) in porous media, with applications to packed beds and metal foams. The motivation of this study to achieve a significant enhancement in thermal efficiency and heat transfer rates (HTRs) for advanced engineering applications. Compared to mono and binary nanofluids, these nanofluids provide better heat regulation and greater thermal conductivity by mixing Ag,Al2O3, graphene nanoparticles in a base fluid. Because it provides better heat transfer and flow stability than traditional fluids and binary hybrid nanofluids, this work is important for the design of high-efficiency thermal management systems. A 3D solution of transformed governing equations is obtained by using Galerk in finite element method. Fluid velocity f'(η) increases with rise in curvature parameter Ω while it whittles down with rise in slip parameter γ at low Reynolds number subject to uniform and linear heating in low porosity porous media (packed bed of small particles) and high porosity porous media (metal foam). Further, fluid temperature θ(η) for THNF is greater than that of hybrid nanofluid (HNF) in both boundary heating subject to both type of porous media.
