A numerical study of the collapse of a bubble in a three-component, three-phase system is presented. The heat transfer is modeled using a quasi-steady integral boundary layer approach while the concentration profiles of noncondensibles are determined by solving the transient diffusion equation. It is shown that the experimentally determined collapse of small bubbles (between 1-mm and 3-mm initial radius) agrees with the model, while larger bubbles, which deform during their early history, are better described by a uniformly distributed noncondensible model.
