Significance of Fe₃O4/MnZnFe₂O₄ nanoparticles for thermal efficiency of ethylene glycol: Analysis for single-phase nanofluid flow using Cattaneo Christov theory

Thermal conductivity of nanoparticles is a vibrant parameter in the heat transfer applications applied in thermal, mechanical and chemical engineering. The use of nanoparticles in the conventional fluids augments the thermal conductance which directly affects the heat transfer mechanism. It greatly depends on the nature of nanoparticles. Hence, the excellent conductivity of hybrid Fe 3 O 4 /MnZnFe 2 O 4 allows to select for catalytic agent with EG as primary solvent for heat transfer applications. Besides nanoparticles, the physical phenomena like heating species, Cattaneo Christov thermal flux and variable temperature of the surface potentially alter the performance of single phase nanofluids. Therefore, the current effort aims to formulate a single phase problem through slanted elongating surface having acute angle with the ground level and influenced parametric ranges. The final problem was examined numerically (shooting scheme coupled with RK scheme) and then analyzed and predicted the ranges for better performance. The parallel results reveal that the nanofluid movement is slower than common fluid over the domain because of dominant denser effects. The heat generative parameter ([Formula: see text] and radiation number ([Formula: see text] are observed to be excellent catalytic parameters to boost the model efficiency. However, thermally radiative nanofluids are more efficient which augment the performance remarkably. The shear drag improved from [Formula: see text] to [Formula: see text] (for [Formula: see text], [Formula: see text] to [Formula: see text] (for [Formula: see text] against [Formula: see text] to [Formula: see text]. Further, the heating source Q enhances the heat transport rate at the slanted surface from [Formula: see text] to [Formula: see text] (for [Formula: see text], and [Formula: see text] to [Formula: see text] (for [Formula: see text]. However, it is prevailing for [Formula: see text] for specified values of Q.
