RETRACTED: Effects of wavy porous fins on the flow, thermal fields, and entropy of the magnetic radiative non-Newtonian nanofluid confined inclined enclosures

Abstract

In this paper, the numerical investigation on the micropolar non-Newtonian nanofluid transient flow within inclined enclosures containing wavy porous fins is carried out. Electromagnetic forces together with thermal radiation are taken into account. Also, the impacts of the Brownian motion and thermophores on the suspension flow are surveyed. The finite volume method is employed to solve nonlinear coupled partial differential equations. The enclosure is partially heated from below and the second law of the thermodynamic is analyzed. The cases where the microelements close to the boundaries are unable to rotate are assumed and a heat source/sink is taken place within the flow domain. The main outcomes revealed that the presence of the radiation enhances the convection situation while the heat generation and vortex parameters reduce the heat transfer rate. Also, there is a diminishing in the rate of the heat transfer up to 5.62% when the Hartmann number is altered from 0 to 50. This numerical investigation is germane to the engine lubricants, paint rheology, turbulent shear flows, direct absorption of the sunlight in solar collectors, cement slurries, and combustion chambers.
