Study on dynamics and structure of evaporation front in ethanol depending on pressure and subcooling

This paper is dedicated to study of self-sustained evaporation front in subcooled ethanol at stepwise heat generation. The data on evaporation front velocity and microstructure at different subcoolings and pressure are presented. Experiments show that development of the evaporation front drastically depends on studied parameters. At low pressures initial vapour bubbles grow without losing interface stability and initiation of evaporation fronts doesn’t occur. At higher pressures the fronts propagate along the heater, and its structure depends on temperature.
