PREDICTION OF FLOW FIELDS GENERATED BY RUSHTON TURBINE
摘要
Abstract
Two sets of instantaneous flow fields generated by a Rushton turbine are simulated in the rotating reference coordinate based on standard k-ε turbulent model.The model predictions successfully reproduce the “two circulation loop” flow pattern in a Rushton turbine stirred tank. The simulation-results also show that the radial flow pattern is transferred to axial flow pattern at C/T*#=*#0.167. The model prediction power number (Np) and the impeller flow number (Nqd) are in good agreement with the experimental data. The model prediction velocity distributions of this study agree with experimental measurements，and are in closer agreement with the experimental data than those based on “block box” method.关键词
