Computational modeling of magnetized hybrid nanofluid flow and heat transfer between parallel surfaces with suction/injection

Abstract

The transfer of heat and mass through the flow of a hybrid nanofluid (Hnf) with the influence of a magnetic field between two rotating parallel plates has been studied. The hybrid nanofluid (Hnf) is created by dispersing nanoparticles (NPs) of Al2O3 and Molybdenum Disulfide (MoS2) into ethylene glycol (ETH). MoS2 is commonly used as an anti-friction agent in various heavy machinery, including automobiles. It decreases engine noise, improves fuel efficiency, and extends the engine's lifespan. Likewise, Al2O3 finds applications in structural materials, food processing, and pharmaceutical industries and serves as an electrical insulator in microelectronic devices. An alternative numerical method compares the findings for velocity, energy, and concentration profiles. Moreover, the velocity field diminishes as a result of the impact of the Reynolds number and the suction/injection factor. The presence of higher amounts of MoS2 and Al2O3NPs in the EG leads to a decrease in fluid velocity.
