Impact of the Gas Phase on the Properties of Foams

A better understanding of the impact of gas on foam can enable designing a foam system with desirable properties for applications ranging from enhanced oil recovery to preparation of food and beverages. In this work we have explored the effect of different gases on foam generation, coalescence and drainage using different pore-size spargers to vary bubble size. We have also demonstrated new measurements of foam drainage as a function of bubble size, and shown that they agree with a simple theoretical model. The results have potential benefits process improvement.
