Onset of convection in a multicomponent fluid layer in the presence of a uniform magnetic field

Resumo

The principle of the exchange of stabilities for magnetohydrodynamic multicomponent convection is established. If this sufficient condition holds and there are perturbations, oscillatory motions of neutral or growing amplitude can exist in the fluid. The upper bounds for the complex growth rate of such motions when at least one of the boundaries is rigid are obtained.
