Optimizing performance of ternary nanoparticles in enhancing thermal transport between permeable coaxial cylinders with interfacial nanolayer

Superiority in heat transfer performance is a crucial factor in attaining enhanced technological and engineering production. Scientists have assessed the distinct thermophysical properties of three multi-structured (ternary) nanoparticles and proposed their compositions. Liquids with enhanced thermal properties with the addition of ternary nanoparticles are widely used in nuclear power reactors, electronics, energy storage, solar panels, and collectors. The influence of a novel interfacial nanolayer generated between the induced nanoparticles (Cu, Al₂O₃, and TiO₂) and the host base liquid (water) flow between two coaxially rotating cylinders is a novel subject of current communication. Physical influences of permeability and magnetic field are also envisaged. A suitable collection of transformations is applied to alter the non-linear PDE’s setup into ODE’s. To solve complex coupled system that has been built, the shooting approach along the RK method is implemented. From a comparative perspective, the consequences are viewed in illustrative and data structures relative to the parameters involved. To guarantee the accuracy of calculations, a comparison of results for related quantities (Nusselt and skin friction) is also included. When the interfacial nanolayer thermal conductivity model is applied instead of another, a 50% increase in the heat flux is observed. Skin friction along tangential and radial direction tends to decrease versus elevation in magnitude of nanoparticle volume fraction. Equal dispersion of ternary nanoparticles up to \(5\boldsymbol{\%}\) $5\mathbf{\%}$ , yields less significant uplift in Nusselt number in comparison to non-equally dispersion of ternary nanoparticles. Nanolayer impact with incorporation of ternary nanoparticles through a porous surface has achieved 33% increment in thermal conductivity as compared to simple thermal conductivity model.
