    "abstract": "The occurrence of swarms of small bubbles in a variety of industrial systems\nenhances their performance. However, the effects that size polydispersity may\nproduce on the stability of kinematic waves, the gain factor, mean bubble\nvelocity, kinematic and dynamic wave velocities is, to our knowledge, not yet\nwell established. We found that size polydispersity enhances the stability of a\nbubble column by a factor of about 23% as a function of frequency and for a\nparticular type of bubble column. In this way our model predicts effects that\nmight be verified experimentally but this, however, remain to be assessed. Our\nresults reinforce the point of view advocated in this work in the sense that a\ndescription of a bubble column based on the concept of randomness of a bubble\ncloud and average properties of the fluid motion, may be a useful approach that\nhas not been exploited in engineering systems.",
