Investigation of the Stability of Ferromagnetic Viscoelastic Fluid Heated and Soluted from Below Sat

The convection of viscoelastic fluids in a porous media in the presence of a solute parameter is the subject of this study. The oscillatory Rayleigh number is observed to decrease when the stress-relaxation parameter is increased, indicating that the stress-relaxation parameter has the effect of delaying the beginning of convection in a viscoelastic ferromagnetic fluid saturating a porous medium. Furthermore, as the parameter is increased, the Rayleigh numbers for the stationary and overstable cases fall, indicating the destabilising influence of non-buoyancy magnetization on the system. For both stationary convection and overstability, graphs were generated by assigning numerical values to the parameters accounting for magnetization parameter, solute parameter, magnetization parameter, stress-relaxation time parameter, strain-retardation time parameter, and medium porosity.
