Featuring Hall effect on gravity-driven hybrid nanofluid flow induced by rotating cylinder

The progressive nature of hybrid nanomaterials makes them highly valuable in both engineering and industry. Hybrid nanofluids offer a great deal of potential for use in heat transport applications such as vehicle cooling and solar energy systems. This study considers the Hamilton-Crosser’s model to examine the electrical and thermal conductivities of copper and aluminum oxide nanoparticles drenched in water, which acts as a base fluid. The study examines mixed convection with linear radiation and Hall effect. The similarity transformations convert the governing equations into dimensionless ordinary differential equations. These equations are then solved numerically in MATLAB’s built-in technique namely, bvp4c by variation of physical parameters. The novelty of the study includes investigation of the thermal behavior of hybrid nanofluids by integrating nanoparticles into base fluid to attain enhanced heat transfer rate, along with the analysis of mixed convection and Hall effect over a rotating cylinder. Graphical illustrations show the behavior of various parameters over fluid flow, temperature profile, drag fraction, and heat transfer rate.
