“…5). As P increases, the velocity of the TC flow also increases [7] and the influence of boundaries on it must be more marked. When the power of the laser beam increases, the total curvature of the liquid surface in both directions becomes larger due to increasing dynamic curvature of the TC depression, and both focal distances, f i and f b , decrease (Fig.…”

A thermocapillary depression is induced by a laser beam in a layer of a transparent liquid on an absorbing substrate. Two plane-parallel wettable plates are immersed in the liquid in symmetrical positions with respect to the point of incidence of the beam on the liquid. The diameters of the thermocapillary response formed by the laser beam on a screen are studied in their dependence on the curvature of the equilibrium liquid meniscus formed between the plates. The property of additivity is experimentally proved; according to this property, the curvature of the free liquid surface is equal to the algebraic sum of the static curvature of the wetting meniscus and the dynamic curvature of the thermocapillary depression.

“…Indeed, as the power of the light beam increases, the velocity of the TC flow becomes higher [7]. In this case, the effect of the plates on the velocity of the flow directed across them must also increase and curvature χ b must decrease by a greater value.…”

“…Closed flows in the form of thermocapillary vortexes appearing under the heating of melt or liquid surfaces by cw laser radiation were investigated, for example, in paper [1]. The main features of unclosed flows, which appear under the action of the force of gravity and the recoil momentum of vapours during the melting of vertical metal targets by the radiation of cw and repetitively pulsed CO 2 lasers, were studied in [2,3].…”
