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

This is the authors' abstract. We don't add key points for this paper.

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.
