THERMAL SINGULARITIES IN FILM RUPTURE

Long-wave approximation for the spatiotemporal evolution of thermal an d evaporative instabilities of a thin liquid film lying on a ''thick'' solid substrate is considered. It is shown that accounting for a nonz ero thermal resistance of the solid eliminates the emergence of temper ature, heat and mass flux singularities at the rupture point.
