摘要：

The application of large eddy simulation (LES) to the prediction of large-scale chaotic structures in stirred tanks is investigated. Flow regimes representing typical stirrer configurations were assessed: a single radial pumping impeller and a single axial pumping pitched blade turbine. The turbulent flow field in each configuration was calculated using LES turbulence models. The impellers were modeled using the sliding mesh model. The predicted flow patterns compared well with digital particle image velocimetry data reported in the literature, and exhibited the long time scale instabilities seen in the experiments. The results of these studies open the way to a renewed interpretation of many previously unexplained hydrodynamic phenomena that are observed in stirred vessels.
