INTERACTION BETWEEN SHORT-SCALE MARANGONI CONVECTION AND LONG-SCALE DEFORMATIONAL INSTABILITY

Nonlinear evolution of two interacting modes of the Marangoni convecti on, a long-scale deformational mode and a short-scale stationary conve ctive pattern, is considered. It is shown that the interaction between modes stabilizes surface deformation and leads to formation of variou s convective structures: stationary long-scale modulated roll patterns , traveling and standing long waves, and can also cause chaotic convec tion (interfacial turbulence).
