Magneto Rotatory Double –Diffusive Kuvshiniski ViscoelasticFluid through a Porous Medium

Abstract

The effect of magnetic field on an incompressible (Kuvshiniski – Type) viscoelastic rotating fluid heated and soluted from below is considered. For the case of stationary convection medium permeability and stable solute gradient have destabilizing and stabilizing effect on the thermosolutal convection. Magnetic field and stable solute gradient have stabilizing effect, where as medium permeability has destabilizing effect in absence of rotation and having both stabilizing as well as destabilizing effect in the thermosolutal kuvshiniski viscoelastic rotating fluid. It is also found that rotation, magnetic field and stable solute gradient introduce oscillatory modes in the system, where as in their absence principal of exchange of stabilities is satisfied. Graphs also have been plotted by giving some numerical values to the parameters.
