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.7 pagesPDFenUniversity of PretoriaCavitation processesHEFAT8th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics 2011Heat transferThermodynamicsFluid mechanicsBinary systemsNucleation rateClassical nucleation theoryCNTMulti-component formExperimental dataPresentation
