The characteristics of convection in liquid layers heated below the free surface are numerically studied. The mechanisms for convection are buoyancy and variation of surface tension with respect to temperature. Specific computations are performed to stress the influence of heat transfer at the interface and of interfacial viscosities. The transition between Marangoni and buoyancy regimes, when heating by an infinite hot wire located below the free surface, is investigated.
