Structure of a pure-vapor/liquid contact line on a heated substrate: truncated adsorbed microfilms and the spreading coefficient

With the disjoining pressure in the form of an inverse cubic law, steady configurations of an evaporating liquid film are studied such that at one end it approaches a microfilm starting abruptly as a square root of the coordinate while getting to a constant slope at the other. The parameters are associated with the spreading coefficient in the manner of de Gennes. There exists a positive critical value of the spreading coefficient. For the values above the critical one, the microfilm turns into a semi-infinite one of constant thickness. For the values balow the critical one, a kink formed by such a microfilm recedes along the solid surface.
