Abstrakt

The growth or collapse of vapor bubbles from a finite, initial size in a binary liquid mixture is studied under conditions that both heat and mass transfer are the controlling mechanism. The influence of translatory bubble velocity is given particular attention. It is disclosed that the translating velocity and its surface temperature and composition are time-dependent. Translatory bubble motion is shown to cause a significant increase in the growth-rate which also results from an increase in the Jakob number. The results are employed to interpret the boiling of binary liquid mixtures where there exists a minimum growth-rate constant or a maximum heat flux at a certain composition.
