Gas dispersion in stirred tank is an important factor for gas-liquid reaction. So far, the study concentrates on experimental research and numerical simulation of single Rushton turbine. Very few numerical simulation researches on the gas-liquid flow in stirred tanks with multiple impellers were reported by using Computational Fluid Dynamics (CFD).
Based on the Euler-Euler two-phase flow model, standard k-e turbulent model and multiple frames of reference (MFR) method, gas-liquid system was simul...
