Mixed convective magnetized GO‐MoS2/H2O hybrid nanofluid flow about a permeable rotating disk.

The primary objective of the present numerical analysis is to investigate the effect of a mixed convection flow around a disk containing hybrid nanofluid as graphene oxide (GO)‐molybdenum disulfide (MoS2) nanoparticles and water (H2O). This study examines the impacts of surface suction/injection, slip effect, magnetohydrodynamic effect, the shape of nanoparticles, and heat transfer characteristics, on a disk is analyzed. This research applies to disk‐shaped structures in aeronautical engineering, geophysics, and nuclear engineering, such as core catchers in nuclear power plant steam turbines, waxy crude oils or food products in centrifugal pumps, turbo‐machinery, and other industrial processes. Nonlinear partial differential equations (PDEs) with subjected surface restrictions represent this study's governing equations. It's a PDE. The Von Karman transformation can simplify PDEs into non‐dimensional ordinary differential equations, which can be solved using the MATLAB bvp5c function. The research findings indicate that the presence of hybrid nanoparticles results in a significant increase in the heat transfer rate compared to that of the nanoliquid. Increasing the strength of the magnetic field slows down the flow of a hybrid nanofluid. The gradient value pronounces impacts with increasing slip factor. The heat transfer rate increases significantly with the increase of sphericity of the nanoparticles. [ABSTRACT FROM AUTHOR]
