Abstract

The paper reports on recent experience with the Large-Eddy Simulation approach applied to a turbulent, vertical mixing layer laden with bubbles at low void-fraction. The subgrid-scale modelling is based on the Smagorinsky kernel in both its original form and the dynamic procedure of Germano A new model is proposed for possible bubble-induced turbulence modulation in which the mixing-length of the dispersed phase at the subgrid-scale is inferred dynamically from the resolved flow field. Overall, the LES approach shows considerable promise in regard to predicting the mean quantities including phase velocities and void fractions.
