Large Eddy Simulation of a bubble plume

The paper presents Euler-Euler Large Eddy Simulations (LES) of dispersed bubbly flow in a rectangular bubble column. The flow is characterized by a low Reynolds number. The set of physical models describing the momentum exchange between the phases was chosen according to previous experiences of the authors. The emphasis of the study is the analysis of bubbly flows concerning the investigation of the influence of the subgrid-scale model and the bubble induced turbulence model. It was found that the presented modelling combination provides good agreement with experimental data for the mean flow and liquid velocity fluctuations. The energy spectrum obtained from the resolved velocity is presented and discussed.
