Magneto-Hydrodynamic Flow of a Viscous Fluid in a Channel with a Porous Bounding Wall of Different Permeabilities

Abstract

In this paper, the effects of permeability parameter on the magneto-hydrodynamic laminar flow of a viscous incompressible fluid in a channel with a porous bounding wall have been investigated. A transverse magnetic field has been applied in the channel flow of viscous fluid and the stream function is used to reduce the governing partial differential equations into non-linear ordinary differential equation which is solved by applying Perturbation method. Numerical simulation is used to analyze the problem and the graphs have been plotted using MATLAB. It has been observed that an increase of magnetic parameter increases the velocity of the viscous fluid while the velocity decreases with the increase of permeability parameter. The flow of viscous fluid has also been investigated with the variation of Reynolds number and the slip coefficient.

Heat Transfer in Hydromagnetic Flow over an Unsteady Stretching Permeable Sheet

“…Recently, hydromagnetic flow through unsteady stretching sheet was investigated by Mabood and Khan (2016), and Tian et al (2017). Until, very recently, some scientists and researchers like as , Dey (2019), Pandya et al (2019), andDutta et al (2019) explored the fluid flow analysis with the magnetic impact.…”
