Query: Driving convection by a temperature gradient or a heat current   Bifurcation properties, stability behavior, dynamics, and the heat transfer
of convection structures in a horizontal fluid layer that is driven away from
thermal equilibrium by imposing a vertical temperature difference are compared
with those resulting from imposing a heat current. In particular oscillatory
convection that occurs in binary fluid mixtures in the form of travelling and
standing waves is determined numerically for the two different driving
mechanisms. Conditions are elucidated under which current driven convection is
stable while temperature driven convection is unstable.
