摘要: The gas-liquid flow field in a stirred tank with a Rushton disk turbine, including the
impeller region,was numerically simulated using the improved inner-outer iterative
procedure. The characteristic features of the stirred tank, such as gas cavity and
accumulation of gas at the two sides of wall baffles, can be captured by the simulation.
The simulated results agree well with available experimental data. Since the improved
inner-outer iterative algorithm demands no empirical formula and experimental data for the
impeller region, and the approach seems generally applicable for simulating gas-liquid
stirred tanks.
