At high values of Oh, viscous dissipation prevents drop ejection; whereas at low values of Oh, the primary drop is accompanied by a large number of satellite droplets. Similar to the formation of stable drops influenced by viscous effects, we propose that stable gas bubbles may arise when the Oh number falls within the range of 0.1 to 1. At higher Oh values, viscous dissipation impedes bubble formation, while at lower values, numerous small bubbles may form, but they will not remain very stable. As indicated in the Results section, when fitting foaming results from shake test experiments, we observed that the upper limit of Oh = 1.22 yielded more accurate predictions for foaming. This led to the following equation for formation of stable bubbles, used in predicting foaming:
