Modulation of energy transport in stagnation point flows involving hybrid nanofluids

Proceedings of the Institution of Mechanical Engineers Part N Journal of Nanomaterials Nanoengineering and Nanosystems, Journal Year: 2025, Volume and Issue: unknown

Published: March 25, 2025

The study of stagnation-point flows holds significant importance due to their practical engineering applications. This examines the flow and heat transfer characteristics induced by bi-linear axial stretching a heat-generating surface within an electrically conducting hybrid nanofluid comprising alumina, copper nanoparticles suspended in pure water. is subjected convective strain rates, generating three distinct types: Hiemenz (radial stretching), Wang, Howarth (orthogonal) stagnation point flows. brick shaped are considered using Hamilton Crosser’s model. Numerical simulations acquired through bvp4c, it reveals that increasing Lorentz force reduces velocity but enhances drag force. Variation Biot number indicates more efficient transfer, which increases temperature fluid as was transferred from into fluid. Additionally, influence controlled parameters on thermal profiles assessed, provide insights optimizing reducing skin industrial applications requiring management.
