Abstract

The modified Young-Neumann conditions in view of the linear tension are formulated on the line of contact between the three media. The formula for an estimate of value of the linear tension in terms of real measurable quantities is given. It is shown that the contribution of the linear tension is related to aspiration of heterogeneous system to reduce length of a boundary of phases, and with its curvature, and should be considered at the small sizes of drops. Using an example of a spreading of a volatile drop on other fluid, it is shown experimentally and theoretically, that for small drops a role of a gravity force and the surface tension becomes negligibly small in comparison with the linear capillary effects.
