On the shape of self-sustained evaporation front in a metastable liquid

Abstract

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