【 摘 要 】

A binary formulation of the classical nucleation theory (CNT) is developed for homogeneous bubble nucleation in systems composed of a liquid solvent and a dissolved gas. The CNT predictions coincide with experimental nucleation data from the literature for diethylether/N2and isobutane/CO2mixtures, while several inconsistencies are identified for propane/CO2and R22/CO2experimental datasets.
