Effects of temperature oscillation on unsteady MHD hybrid nanofluid motion over a semi‐infinite moving vertical sheet

Abstract

AbstractThis paper explores the impacts of temperature oscillation and Lorentz force on the two‐dimensional transient hybrid nanofluid boundary layer motion over a semi‐infinite moved vertical sheet with energy transfer. The fluid considered here is viscous and incompressible, and partial differential equations model the problem with appropriate boundary conditions. The implicit finite difference numerical technique is employed to define unconditionally stable computational solutions to this challenge. Variations of thermal and hydrodynamic structures and the corresponding engineering quantities are explored in terms of magnetic parameter, Grashof number, phase angle, and nanoparticles concentration via graphs. It has been found that with an increment of nanoparticle volume fraction φ2, the friction parameter decreases and the strength of energy transport increases. Furthermore, a reduction of friction coefficient Cf and local Nusselt number Nu can be found by increasing the magnetic field parameter M or phase angle ωt. The findings can be applied to a variety of engineering devices, such as thermal exchangers, solar collectors, and bioreactors.
