Abstract

Periodic regimes of large-scale convection in a two-layer system with a deformable interface are considered. In the limiting case of strong surface tension, an amplitude equation describing the interface deformation is derived. Two-dimensional periodic flow regimes are studied. It is shown that, depending on the governing parameters, both hard and soft excitation of convection is possible. In the presence of heating from above, the finite-amplitude excitation of convection was observed.
