Hydromagnetic Instability of Stratified Rivlin-Ericksen Fluid in Porous Medium in the Presence of Suspended Particles
The stability of stratified Rivlin-Ericksen fluid in porous medium in the presence of suspended particles and magnetic field has been investigated. Upon application of normal mode technique, the dispersion relation was obtained. The important results obtained in this paper include the instability of non-oscillatory modes and the stability of oscillatory modes. Also, it was found that the system...
متن کاملThermal Instability of Compressible Walters’ (model B ) Fluid in the Presence of Hall Currents and Suspended Particles
Effect of Hall currents and suspended particles is considered on the hydromagnetic stability of a compressible, electrically conducting Walters’ (Model B ) elastico-viscous fluid. After linearizing the relevant hydromagnetic equations, the perturbation equations are analyzed in terms of normal modes. A dispersion relation governing the effects of visco-elasticity, magnetic field, Hall currents ...
متن کاملInstability in Walters B’ Viscoelastic Dusty Fluid through Porous Medium
A detailed account of the theoretical and experimental study of thermal instability (Bénard convection) in Newtonian fluids, under varying assumptions of hydrodynamics and hydromagnetics, has been treated in detail by Chandrasekhar [1]. The use of Boussinesq approximation has been made throughout, which states that the density may be treated as a constant in all the terms in the equations of mo...
متن کاملThe effect of rotation and magnetic field on thermal instability of compressible Walters’ B′ viscoelastic fluid
The thermal convection of compressible Walters’B′ Rotating viscoelastic fluid is considered in the presence of uniform vertical magnetic field. By applying normal mode analysis method, the dispersion relation has been derived and solved analytically. For stationary convection, Walters’B′ viscoelastic fluid behaves like an ordinary (Newtonian) fluid. It is found that rotation has a stabilizing e...
متن کاملThermal Convection of Rotating Micropolar Fluid in Hydromagnetics Saturating A Porous Medium
This paper deals with the theoretical investigation of the thermal instability of a thin layer of electrically conducting micropolar rotating fluid, heated from below in the presence of uniform vertical magnetic field in porous medium. A dispersion relation is obtained for a flat fluid layer, contained between two free boundaries using a linear stability analysis theory, and normal mode analysi...
