Significance of Marangoni convection and heat generation on Darcy Forchheimer 3D flow of Maxwell \((\text{AA}7072+\text{AA}7075-{\text{CH}}_{3}\text{OH})\) hybrid nanofluid over a rotating disk

Abstract

The current model describes the study of Darcy–Forchheimer 3D flow of MHD Maxwell hybrid nanofluid over a rotating disk with Arrhenius activation energy, heat generation, and variable thermal conductivity and mass diffusivity, taking into account with the effects of Marangoni phenomena. A hybrid nanofluid consisting of \(AA7072\) and \(AA7075\) aluminum alloys nanoparticles, methanol as the base fluid is used. The \(AA7072\) alloy is a composition of silicon, ferrous, and copper added to aluminum and zinc in the ratios of \(98:1.\) Similarly, \(AA7075\) is a combination of \(\sim 90, \sim 6, \sim 3\), and \(\sim 1\) aluminum, zinc, magnesium, and copper, with silicon ferrous and magnesium added. In aerospace engineering, it could help with the planning and refinement of turbine blade cooling systems, guaranteeing effective heat dissipation and extended component life. The model's findings in materials science could improve the creation of sophisticated cooling solutions for high-performance electronics, enhancing the control of thermal expansion in components like electric car batteries and computer processors. The bvp4c approach is used to numerically solve the resulting non-dimensional equations. As the Marangoni convection parameter rises, the concentration and temperature distributions drop while the rates of heat and mass transfer in both hybrid nanofluid and nanofluid increase.
