摘要：
The study relates to the power consumption, mixing time and mixing efficiency defined as the product of the mixing time and the power consumption in a non standard vessel equipped with various axial and mixed dual-impeller configurations. The effects of the rotational speed, gas flow rate, impeller type and diameter are investigated. The mixing mechanisms are found strongly dependent on flow patterns, impeller type and diameter. Dimensionless correlations are proposed to predict power consumption and the mixing time beyond complete dispersion regime. (C) 2001 Elsevier Science B.V. All rights reserved.
