چکیده مقاله:
The effect of magnetic field on an incompressible (Kuvshiniski-type) viscoelastic rotating fluid heated from below in porous medium is considered. For the case of stationary convection, magnetic field andmedium permeability have both stabilizing and destabilizing effect on the thermal convection undersome conditions whereas rotation has a stabilizing effect on the thermal convection. In the absence of rotation, medium permeability has a destabilizing effect while magnetic field has a stabilizing effect on the thermal convection in a Kuvshiniski viscoelastic rotating fluid. It is also found that presence ofmagnetic field and rotation introduce oscillatory modes in the system, whereas in their absence principle of exchange of stabilities is satisfied in the system. Graphs also have been plotted by giving some numerical values to the parameters.
