Abstract
The effect of magnetic field on an incompressible Kuvshiniski 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 double- diffusive convection. Magnetic field and stable solute gradient have stabilizing effect, where as medium permeability has destabilizing effect in absence of rotation and in presence of rotation having both stabilizing as well as destabilizing effect in the double- diffusive convection of kuvshiniski viscoelastic 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.
