Non-Fourier thermal and mass transport in hybridnano-Williamson fluid under chemical reaction in Forchheimer porous medium

Williamson stress-strain correlations are shear rate dependent correlations and describe the rheology of various polymers. In this article, generalized non-Fourier models are utilized here in this investigation to study heat and mass transport in Williamson fluid. The effect of a suspension of nano-sized hybrid particles on the thermal efficiency of the MoS₂−SiO₂−Williamson fluid is also examined. The Williamson fluid is assumed to exhibit thermal relaxation behavior due to which fluid avoids thermal changes in order to maintain its thermal equilibrium. Due to this characteristics fluid exhibits a decrease in its temperature field when thermal relaxation times of MoS₂−SiO₂−Williamson fluid and MoS₂-Williamson fluid. Simulations have shown that MoS₂-Williamson fluid has thermal relaxation time greater than the thermal relaxation time of MoS₂-SiO₂-Williamson fluid. Darcy and Forchheimer porous media are responsible for controlling boundary layer region due to the resistive force among the fluid particles and porous medium.Simulations can also be used to compare the resistive force exerted by the Darcy and Forchheimer porous medium. In terms of managing the momentum boundary layer, Forchheimer porous media is determined to be more effective than Darcy porous medium. Shear thinning and shear thickening behavior have significant decreasing and increasing impacts on the motion of fluid particles, respectively. It is also found from numerical simulations that effective thermal conductivity of hybrid nanofluid (MoS₂−SiO₂−Williamson fluid) than that of mono nanofluid (MoS₂-Williamson fluid). As a result, hybrid nanofluid is proposed for enhanced heat energy transmission. It's also discovered that hybrid nanofluid generates less heat than mono nanofluid. Solutal relaxation time (relaxation time associated with solute transport) has shown decreasing impact on concentration field. The solutal relaxation period of a MoS₂−SiO₂−polymers is longer than that of a MoS₂-polymer, according to numerical experiments. In both MoS₂-polymer and MoS₂−SiO₂−polymers, the influence of destructive chemical reactions on mass transport is the polar opposite of the impact of generative chemical reactions on mass transport in both types of fluid regimes. The effect of generative chemical reactions on mass mobility is analogous to the effect of heat generation on temperature. In a hybrid nanofluid, heat and mass fluxes are higher than in a mono nanofluid. Thus if hybrid nanofluid rather than mono nanofluid, for cooling systems as heat conducting material (working fluid) then efficiency of cooling system will be much improved.
