Stability of Double- Diffusive Hydromagnetic Walter’s (Model B’) Visco- Elastic Fluid Permeated with Suspended Particles and Variable Gravity in Porous Medium

Abstract

The problem of double- diffusive hydro magnetic instability of Walter’s (Model B’) visco-elastic fluid permeated with suspended particles and variable gravity in porous medium is considered in the presence of rotation. It is found that principle of exchange of stabilities is valid under certain conditions. For stationary convection, the Walter’s (Model B’) visco-elastic fluid behaves like a Newtonian fluid.  The effect of magnetic field has been shown graphically also.
