Effects of relaxational diffusion in film boiling of a polymer solution

Effects of relaxational diffusion during rapid evaporation of a solvent from a polymer solution taking place as a result of a thermal shock from the side of the free surface of the liquid are investigated. It is shown that, as a result of diffusional resistance to evaporation, a polymer-enriched layer is formed in the vicinity of the phase interface that can stabilize substantially the shape of the phase interface.
