Enhancing thermal transport in industrial applications: A study on AA7072–AA7075 hybrid nanofluid over a stretching cylinder with MHD and heat source/sink effects

The role of nanofluids is beneficial for various thermal transport processes such as coolers, pharmaceutical operations, heat exchangers, fuel cells, machining, industries, transportation, and hybrid engines. Stretching cylinders are important in metal and plastic extrusion processes. Such processes involve high temperatures. A theoretical investigation on heat transfer with the fluid flow for a tangent hyperbolic hybrid nanofluid composed of AA7072 and AA7075 nanoparticles dispersed in water across a stretching cylinder in a porous medium. The investigation considers the influence of a magnetic field, heat source/sink effects, and suction/blowing at the cylinder surface. The governing equations, incorporating activation energy effects, are numerically solved using the bvp4c technique. Graphical and tabular results are presented for skin friction coefficient, Nusselt number, and Sherwood number distributions along the cylinder surface. These results highlight significant alterations in temperature and velocity profiles due to magnetic field intensity, heat source/sink parameters, and the characteristics of AA7072 and AA7075 nanoparticles. The velocity profile decreases with increasing the Weissenberg number (We) and suction parameter (S > 0). The temperature profile increases with incrementing values of the thermophoresis parameter (Nt) and Prandtl number (Pr). It also enhanced thermal transfer efficiency. Practically, the insights gained from this research contribute to optimizing heat transfer processes in engineering applications involving porous media, magnetohydrodynamics (MHD), and nanofluids. Socially, advancements in heat transfer technologies may lead to more efficient and sustainable energy utilization, benefiting industries reliant on thermal management. The obtained result has been matched with published articles.
