Abstract
In this Chapter we report on an experimental study of the thermocapillary motion of an aniline drop in an stably stratified fluid system and driven by a laser beam. The thermocapillary motion of drops is the result of the temperature dependence of the interfacial tension. If the surface of the drop is not isothermal gradients of the surface tension appear, which in some cases can move the drop. The source of the no uniformity of the temperature of the surface can be, in particular, the heating of the drop by a laser beam. In the last years, the thermocapillary movement of bubbles and drops under the influence of laser radiation was studied theoretically and experimentally. However, in the literature there is no data on observation of the movement of a single drop in a laser beam. In this paper an experimental methodology is proposed to study such a motion of a drop.
