In accordance with anisotropic feature of turbulent flow

an anisotropic k-ε turbulence model is used to predict the turbulent flow field and turbulent intensity generated by a Rushton disc turbine with the improved inner-outer iterative procedure considering the feature of flow swirl in the stirred tank.The predicted flow patterns are compared with experimental data and the simulation results with the standard k-ε turbulence model.The anisotropic k-ε turbulence model gives better prediction than the standard k-ε turbulence model.The predicted turbulent flow field is in agreement with to experimental data and the trend of the turbulence intensity can be effectively reflected in the simulation.
