Computational assessment of hybrid nanofluid with the rule of heat-transfer enhancement over a stretched sheet: a comparative study

Abstract

Hybrid nanofluids, which incorporate two distinct nanoparticles, are an innovative class of nanofluids designed to improve thermal and mechanical properties. These fluids have garnered considerable interest in numerous engineering and scientific fields. The fundamental goal of this research is to investigate the heat-transfer increase of MnZnFe₂O₄-NiZnFe₂O₄/C₁₀H₂₂ hybrid nanofluids in the presence of magnetohydrodynamics, nonlinear thermal radiation, and the Biot number on a stretched sheet. In this case, nanomaterials (MnZnFe₂O₄ and NiZnFe₂O₄) are combined with a base fluid C₁₀H₂₂. To do this, the system’s partial differential equations are transformed into a set of nonlinear ordinary differential equations using systematic similarity transformations. The shooting approach is then used in combination with MATLAB’s BVP4C solver to solve the resultant ordinary differential equations. The study presents the impact of various physical parameters, including the porosity parameter, magnetic parameter, Prandtl number, thermal-radiation parameter, Biot number, and Schmidt number, on the velocity and temperature fields, illustrated through graphs and tables. The velocity field reduces for increasing values of both magnetic and porosity parameters. The thermal-distribution profile is increased for increasing variations of the temperature-ratio parameter, Biot number, volume fraction of nanoparticles, and the thermal-radiation parameter. The MnZnFe₂O₄-NiZnFe₂O₄/C₁₀H₂₂ hybrid nanofluids combine thermal, magnetic, and fluidic properties, making them versatile for applications in thermal management, medicine, industrial processes, environmental remediation, and advanced sensing technologies. Their multifunctional characteristics provide significant advantages in improving efficiency, performance, and control in various engineering and scientific fields. This research has potential applications in heat transfer, biomedical research, manufacturing, aerospace technology, and beyond.
