Abstract
The purpose of this paper is to study the effects of compressibility,
rotation, magnetic field and suspended particles on thermal stability of a
layer of visco-elastic Walters? (model) fluid in porous medium. Using
linearized theory and normal mode analysis, dispersion relation has been
obtained. In case of stationary convection, it is found that the rotation
has stabilizing effect on the system. The magnetic field may have
destabilizing effect on the system in the presence of rotation while in the
absence of rotation it always has stabilizing effect. The medium
permeability has destabilizing effect on the system in the absence of
rotation while in the presence of rotation it may have stabilizing effect.
The suspended particles and compressibility always have destabilizing
effect. Due to vanishing of visco-elastic parameter, the compressible
visco-elastic fluid behaves like Newtonian fluid. Graphs have also been
plotted to depict the stability characteristics. The viscoelasticity,
magnetic field and rotation are found to introduce oscillatory modes into
the system which were non-existent in their absence.
