Abstract
The article deals with problems of investigation of boiling of liquids - the most intensive heat
transfer phenomena. There are a lot of research reports of boiling dynamics and heat transfer studies
in micro- and nanoscopic levels, carried out with aim to understund phenomena in whole. Simulation
model for vapor bubble growth speed maximum calculations in the region of bubble critical radius is
elaborated. Numerical calculations were carried out for water in the region of system parameters with
the most quantity experimental data available. Maximum of bubble growth speed obtained in region of
2...5 values of bubble critical radius. Dimensionless form of equations allows to perform analysis of
vapor bubble dynamic for different liquids and process physical parameters
