“…The batch mixing time based on the transient response curve was evaluated together with the power consumption of the impeller. As pointed out by some researchers (Prochazka and Landau, 1961;Landau et al ., 1963;Khang and Levenspiel, 1976), however, a description of mixing process and the mixing time are important criteria for characterization. These criteria support discussion of the progress of liquid-phase mixing from quantitative and qualitative viewpoints.…”

“…Irrespective of the agitation mode, mixing proceeded exponentially and completely, S becoming almost zero after an elapsed time. Although the mixing process was described with a unique form of equation (Prochazka and Landau, 1961;Landau et al ., 1963;Khang and Levenspiel, 1976), the expression seems to differ owing to its stage relating to the mixing mechanism (Bourne et al ., 1992). Additionally, the pattern of the mixing process, which the plot in Fig.…”

For an unbaffled agitated vessel with an unsteady forward-reverse rotating impeller, whose rotation reverses its direction with a constant angular displacement, the progress of liquid-phase mixing was studied experimentally in relation to the characteristics of the liquid flow produced by the impeller. The forward-reverse rotating disk turbine impeller with six flat blades has about 1.5 times the shear level of a unidirectionally rotating impeller of identical design. The turbulence generated in the liquid was more intense within the vessel agitated by the forward-reverse rotating impeller. In the forward-reverse agitation mode, the agitation function of the impeller demonstrably enhanced the liquid-phase mixing, which shows a pattern with a higher level of mixedness.  2007
