A description of the self-sustained evaporation-front shape in a layer of metastable liquid

A theoretical model for description of a stationary surface of the self-sustained evaporation front propagating in a layer of superheated liquid flowing over a flat heater is proposed, which takes into account new experimental data. An approximate analytical dependence of the vapor-layer thickness on the coordinate and physical parameters is obtained that satisfactorily agrees with the experimental results. A dimensional parameter is introduced that allows the description to be presented in an invariant dimensionless form.
