Low Reynolds number stability of MHD plane Poiseuille flow of an Oldroyd fluid

Low Reynolds Number Stability of Mhd Plane Poiseuille Flow of an Oldroyd Fluid

The linear stability of plane Poiseuille flow at low Reynolds number of a conducting Oldroyd fluid in the presence of a transverse magnetic field has been investigated numerically. Spectral tau method with expansions in Chebyshev polynomials is used to solve the Orr-Sommerfeld equation. It is found that viscoelastic parameters have destabilizing effect and magnetic field has a stabilizing effec...

Unsteady MHD Thin Film Flow of an Oldroyd-B Fluid over an Oscillating Inclined Belt

This paper studies the unsteady magnetohydrodynamics (MHD) thin film flow of an incompressible Oldroyd-B fluid over an oscillating inclined belt making a certain angle with the horizontal. The problem is modeled in terms of non-linear partial differential equations with some physical initial and boundary conditions. This problem is solved for the exact analytic solutions using two efficient tec...

A Numerical Study on Wire Coating Analysis in MHD Flow of an Oldroyd 8-Constant Fluid

Wire coating process is an industrial process to coat a wire for insulation, mechanical strength and environmental safety. The ever increasing applications in the industrial process are the cause of great interest in the study of viscoelastic flow in the wire coating process in a pressure type die. In the present study we provide a numerical solution of the Navier-Stokes equation for wire coati...

Magnetohydrodynamic (MHD ) Plane Poiseuille Flow With Variable Viscosity and Unequal Wall Temperatures

Feedback Stabilization and Observer Design for Linearized Mhd Channel Flow at Low Magnetic Reynolds Number

We study a 2D and a 3D incompressible magnetohydrodynamic (MHD) channel flow, also known as Hartmann flow, which is electrically conducting and subject to an external transverse magnetic field. We consider periodic boundary condition along one axis (two axis, for the three-dimensional case). We consider the flow at low magnetic Reynolds number and obtain the so-called simplified magnetohydrodyn...
