Abstract

The results of the numerical simulation of weakly-supercritical thermocapillary convection in a thin liquid layer with a free deformable upper boundary and an inhomogeneous nonstationary heat source (a pulsating thermal spot, localized in space and periodically modulated in time) are presented.
