Abstract: A preceding study concluded that the lift force in dense bubble plumes in mixing vessels had no influence on the flow. Since the lift force is generally assumed to be of importance, a new study has been conducted in order to shed more light on the issue. It is found that the lift force seems to be insignificant, but there is some uncertainty in the conclusion.

Keywords: bubbly flow; modelling; CFD; computational fluid dynamics; lift forces; intense stirring; bubble plumes.
