Aspects of mass and thermal relaxation time and exothermic chemical processes on the flow of a ternary hybrid Sutterby nanofluid via slant surface with activation energy and linear convection limits

Abstract

This research scrutinizes the radiative convective heat transfer of non-Newtonian ternary hybrid nanofluid across slant surface of equal quantities of nanoparticles dispersed in raw fluid subjected to a constant magnetic field. The contribution assumes the existence of an exothermic reaction a process of diffusion of nanoparticles of copper metal and metal oxides in the raw liquid to enhance combustion and particle concentration of reactants in chemical processes. The model is governed by thermal and mass relaxation times that appear in partial derivative equations and the mathematical analysis is derived using dimensionless quantities and subsequently solved using the RK45 technique. The computations indicate that both the exothermic reaction and the reaction rate factors increase heat distribution, facilitating the complete combustion process. Tri-nanofluid exerts the highest shear stress on the solid boundary while the minimal shear stress on the surface is seen in the case of mono-nanofluid. A 13.3% upgrade in the thermal efficiency is noticed if tri-nanoparticles are dispersed rather than mono-nanoparticles. Therefore, the significant rise in heat transmit is possible due to the dispersion of tri-nanoparticles.
