Abstract

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.
气相对泡沫材料性能的影响
更好地了解气体对泡沫的影响,可以设计出具有理想性能的泡沫系统,应用范围从提高采收率到制备食品和饮料。在这项工作中,我们探索了不同气体对泡沫产生、聚并和排水的影响,使用不同孔径的喷雾器来改变气泡大小。我们还展示了泡沫排水作为气泡大小函数的新测量,并表明它们与一个简单的理论模型一致。研究结果对工艺改进具有潜在的效益。
