Paper presented at the 8th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Mauritius, 11-13 July, 2011.
The Classical Nucleation Theory (CNT) is applied to nucleation
in cavitation processes in binary mixtures of a liquid component
and a dissolved gas component. The multi-component form of
the CNT allows to study the influence of the dissolved gas concentration
on the resulting nucleation rate. Four binary mixtures
are studied, diethylether – nitrogen, propane – carbon dioxide,
isobutane – carbon dioxide, and chlorodifluoromethane – carbon
dioxide, whose experimental nucleation rates are available in
the literature. The nucleation rates and their dependence on
concentration of the dissolved gas calculated according to the
CNT show good agreement with the experimental data.
