Abstract
The light induced mechanism of bubble clusters formation has been investigated experimentally. It was detected the accumulation of bubbles in the cluster in the light field in almost horizontal closed cell The shape and dimensions of the cluster match the mode structure of the laser spot. The nature of the phenomenon is based on the existence of the thermocapillary forces, which push a suspension of bubbles in a heated area, as well as there are the adhesion forces. The light induced bubble clusters are formed in the case of free-surface liquids also. The dynamical bubble cluster foundation is described on the liquid surface. It is shown that the presence of inhomogeneous heat radiation, effective interaction of bubbles with each other (in the case of free surface) and with the surface of a solid body (closed cells) may lead to the formation of stable bubble clusters at the developed convection.
