Abstract
Bubble dynamics controlled by mass and heat transport in binary systems is investigated by approximate analytical means for the case in which the liquid constitutes a single component and the gas is isothermal. It is found that the transient bubble size can be described by four parameters, and that mass diffusion within the gas significantly limits the rate of the process. The results are in agreement with the growth of stationary nitrogen and helium bubbles in water, experimentally recorded by high-speed photography. Translatory bubble motion is shown to cause a significant increase in the growth rate when the rising bubble has been accelerated and a flow transition has occurred.
