The process of boiling is driven by increasing the heat flux density at the heated wall. It is found that the phenomenon is of a wave character, and the relative propagation velocity of the boiling front is proportional to the heat flux density. An experiment-based correlation to describe the boiling process is also elaborated.  aConvecting flow boiling. 0aHeat transfer. 0aWave phenomena. 0aRefrigeration engineering.  iW :tArchives of Thermodynamics. -gVol. 23, 2002, No. 3, pp. 91-104
