This results from a reduction of bubble size by cleavage, the associated increase in surface area and, additionally, an intensive movement at the bubble interface. The observed phenomena are explained based on flow simulations. The energy required for a oscillating bubble column is less than for a gassed stirred tank.de1522-264020133299302Wiley-VCH VerlagBubble columnsFlow simulationVibration exciterChemieIngenieurwissenschaftenJournal Article10.1002/cite.201200115Journal Article
