Bubble formation in maximum bubble pressure measuring systems employing a gas reservoir of limited volume

摘要

A qualitative analysis of the bubble formation regimes in the maximum bubble pressure measuring system is performed. It is shown that the mechanism of bubble formation at the capillary tip depends on gas supply rate, geometric characteristics of the capillary, volume of the gas reservoir, size of separating bubbles, and the presence of surfactant in the solution. Conditions are defined for which the formation of a bubble series takes place. An approximate expression for the dependence of the bubble number in such a series on the gas supply rate is obtained which is in good qualitative agreement with experimental results.
