Experimental investigation of thermocapillary convection induced by a local temperature inhomogeneity near the liquid surface. 2. Radiation-induced source of heat

The structure and stability of a thermocapillary flow from a concentrated source of heat induced by radiation and located near the free surface of the liquid filling a deep reservoir are experimentally studied. Absolute stability of this flow for all depths and powers of the heat source is found. The profile of the liquid surface near the heat spot is considered experimentally.
