Stability of Stratified Elasto-viscous Walters’ (model B′) Fluid in the Presence of Horizontal Magnetic Field and Rotation
نویسنده
چکیده
The effect of horizontal magnetic field is considered on the stability of stratified viscoelastic Walters’ (Model B′) fluid in the presence of rotation. In contrast to the Newtonian fluids, the system is found to be unstable for small wavelength perturbations for the case of stable stratification. It is also found that the magnetic field stabilizes the certain wave-number band for unstable stratification in the presence of rotation and this wave-number range increases with the increase in magnetic field and decreases with the increase in kinematic visco-elasticity.

Thermal Convection in a (Kuvshiniski-type) Viscoelastic Rotating Fluid in the Presence of Magnetic Field through Porous Medium (TECHNICAL NOTE)
The effect of magnetic field on an incompressible (Kuvshiniski-Type) viscoelastic rotating fluid heated from below in porous medium is considered. For the case of stationary convection, magnetic field and medium permeability have both stabilizing and destabilizing effect on the thermal convection under some conditions whereas rotation has a stabilizing effect on the thermal convection. In the...
