Magnetic micropolar nanofluids flow in double lid‐driven enclosures using two‐energy equation model

Abstract

Impacts of an inclined electromagnetic force on a mixed convective process in two‐sided lid‐driven geometries using the two‐energy equation model are examined in this study. The flow domain is filled by a porous medium and the local thermal nonequilibrium model is applied. Magnetic micropolar nanofluids are assumed as working fluids consisting of water as a base fluid and CuO as nanoparticles. The forced convection situation is due to the moving of the upper and lower walls in the right direction with a constant velocity. The used methodology depends on the finite volume method, together with the SIMPLE algorithm. The obtained outcomes are visualized using contours of the streamlines, isotherms for the nanofluid phase, isotherms for the solid phase, and angular velocity. The main findings revealed that the increase in lengths of the heated parts and the Nield number reduces the Nusselt number for the nanofluid phase. Also, the average heat transfer rate for the nanofluid and solid phases are boosted with the increase in the vortex viscosity.

Effect of the Aligned Magnetic Field over a Stretching Sheet through Porous Media in Casson Fluid Flow

“…In an unsteady laminar magnetohydrodynamics (MHD) convective rotating flow, Aruna et al, [16] investigated the influence of Hall and ion slip on the properties of a second-grade fluid while taking chemical reaction and radiation absorption into consideration. Raizah et al, [17] explored the impact of an angled electromagnetic force on mixed convective processes in two-sided lid-driven geometries by employing local thermal nonequilibrium (LTNE) conditions and assumed a flow domain filled with a porous material in which the working fluids consist of magnetic micropolar nanofluids comprising CuO nanoparticles and water as a base fluid are considered. Motsa et al, [18] investigated the behaviour of impulsively begun vertical porous surfaces in non-Darcian MHD fluid flow.…”

Entropy generation analysis of free convection radiative MHD Eyring–Powell fluid flow between porous parallel plates with Soret and Dufour effects

“…Ahmed and Arafa 24 have described MHD radiative Casson fluid flow over a vertical plate with joule heating. Raizah et al 25 have examined MHD mixed convective micropolar nanofluid flow in double lid driven enclosures using a two energy equation model. Soret and Dufour effects on fluid flows are studied by the authors; Ahmed et al 26 have examined the impact of uniform transverse magnetic field on nanofluid flow between parallel plates.…”
