EMHD Couette Flow of Bingham Fluid Through a Porous Parallel Riga Plates with Thermal Radiation

Abstract

The Numerical study for the unsteady electro magneto-hydrodynamic (EMHD) Couette flow of Bingham fluid through a porous parallel Riga plates with the consideration of thermal radiation has been carried out. The Couette flow is considered where the upper Riga plate moves with a uniform velocity U0 and the lower Riga plate is stationary. An external uniform magnetic field is applied perpendicular to the plates. Both the upper and lower Riga plates are kept at different but constant temperatures T1 and T2. respectively, where T2>T1. The governing equations have been transformed into dimensionless nonlinear partial differential equations by using usual transformations. The obtained equations have been solved numerically by the explicit finite difference method (FDM) under the stability and convergence analysis. The effects of some important parameters on shear stress, Nusselt number including velocity and temperature distributions have been discussed graphically by MATLAB R2015a.

Electro-magnetohydrodynamic flow and heat transfer of a third-grade fluid using a Darcy-Brinkman-Forchheimer model

“…Muhammad et al (2019) explored the EMHD flows with heat transfer using a non-Newtonian fluid model moving through a porous channel. Khatun et al (2019) studied a Couette-EMHD flow using the Bingham fluid model over a Riga plate with heat transfer and porous effects. The study by HFF 31,8 Gayatri et al (2020) discussed the Carreau fluid model with EMHD effects over a stretching surface also with heat transfer.…”
