Thermal radiation and heat source/sink influence on MHD heat transmission of copper (Cu)–aluminum oxide (Al2O3) Hybrid nanofluid flow with velocity and thermal slips along a stretching sheet

Abstract

The primary aim of this study is to examine the Magneto radiative flow characteristics of Hybrid nanofluid, a subject of contention within the framework of a stretching sheet including porous material and a heat source/sink. The remarkable ability of hybrid nanoparticles to enhance heat transmission has fascinated several experts, prompting them to further investigate the properties of the working fluid. This work specifically examines the Hybrid Nanofluid flow with MHD and heat transfer on an elongating surface, taking into account radiation and chemical reaction. The study utilizes a mixture of copper ( Cu ) and aluminum oxide ( A l 2 O 3 ) nanoparticles combined with water ( H 2 O ) as the underlying fluid. The process of similarity conversion is used to translate the governing partial differential equations (PDEs) of the fluid flow model into nonlinear ordinary differential equations (ODEs). The whole set of non-linear coupled ODEs, together with the boundary circumstances, are numerically solved by means of the Keller-Box approach. Two unique fluids, known Cu/water (nanofluid) and as A l 2 O 3 − Cu / water (hybrid nanofluid), are used to investigate the flow factors affecting heat transportation phenomena. Comparing the numerical data with the findings reported in the prior works reveals a strong agreement. This research explores the impacts of convective heat transfer, thermal radiation, heat absorption, and MHD. Nanofluid technology has several technical and industrial uses, including power production, sun collecting, and heat exchangers for cooling. Although nanofluids have the highest heat transfer rate compared to traditional fluids, there are several limitations to their effectiveness.
