Effect of throughflow and magnetic field on Marangoni convection in micro-polar fluids

The effect of throughflow and uniform magnetic field on the onset of Marangoni convection in a horizontal layer of micro-polar fluid bounded below by a rigid isothermal surface and above by a non-deformable free adiabatic surface, for marginal state is studied. The conditions for the onset of instability occurring via stationary convective modes are obtained with the help of Galerkin method. It is observed that both stabilizing and destabilizing factors due to constant vertical throughflow can be enhanced by magnetic field.
