Numerical study of convection phenomenon in hybrid nanofluid flow over vertical rotating cylinder

Abstract

Hybrid nanofluid is a novel nanotechnology fluid created by distributing two distinct nanoparticles into conventional energy transfer fluid. The thermal properties of aluminum alloys, namely AA7072 and AA7075 with engine oil (base fluid) of hybrid nanofluid flow induced over a vertical stretchable rotating cylinder are investigated in this study. The focus here is the analysis of energy transportation in the presence of Joule heating, thermal energy source/sink, thermal radiation and activation energy. Moreover, all energy constraints are analyzed through graphical outcomes, which are computed numerically through bvp4c built-in MATLAB. The significant observation made is that as the Reynolds number and the magnetic field parameter enhance, the flow field declines. Additionally, the convective transport of the thermal energy increases for a higher magnitude of resistive heating and buoyant motion of the fluid. It is also noted that the activation energy in the system decreases for mass diffusion.
