RESUMO

The character of heat exchange in evaporation of a swirled liquid film depends significantly on heat transfer in a vapor gap. Using the developed and tested model, the author carried out a numerical analysis of heat transfer in the vapor gap. It was established that heat transfer from a wall to vapor plays a main role in evaporation, since superheated vapor moves to the central vapor flow. The analysis of the influence of the Re number on heat transfer was carried out.
