摘要：

The previously proposed correlations of power consumption in baffled agitated vessels with paddle and turbine impellers showed some contradictions. The difference of impeller level among the given experimental conditions was believed to cause them. In the present work, the change of power number with the impeller level and the impeller dimensions was investigated experimentally. Then, it was confirmed that the contradictions among the power correlations depended strongly on the impeller level, and that the change of power number with the impeller level was closely related to the change of flow pattern in a vessel. A major factor which influenced this change was experimentally confirmed to be the ratio of impeller level to vessel diameter.
