“…13,19 A somewhat similar design of the bottom blade used in this design is the retreat curve impeller (RCI) typically used by the pharmaceutical industry ( Figure 5-17). 20 The power number for one to four baffles for the Given the impeller power relationship, equation [1], and substituting in Froude's correlation, the power in the full scale can be estimated using equation [9]. Using equation [9] and 0.65 hp for the 31-inch hopper test, the power for the 51-inch hopper is calculated to be 4.16 hp.…”

“…These results of comparisons proved that the energy transmission from the impeller region to the bottom one was potentially successful for vessels with shorter length of baffles to cover the upper half of the liquid phase. In combination with comparable characteristics of impeller discharge as shown in Figure 5, application of such partial baffles to the vessel is expected to be effective for enhancement of the liquidphase mixing with design of the impeller-vessel configuration, including the baffle geometries [36][37][38][39][40].…”

For a vessel agitated by a Rushton turbine impeller, the efficacy of partial baffles was evaluated through examination of the liquid flow and impeller power characteristics. The bulk flow formed a pattern having circulation loops of different intensity and largeness depending on the baffle condition: the baffle length relative to the liquid depth for the vessel. Consequently, the liquid flow within the vessel affected the impeller power number. The characteristic circulation loops, which generally reflect the baffle efficacy, were assessed in terms of the discharge flow through the impeller and the energy transmission within the vessel based on the flow velocity profiles. The shorter length of baffles fitted partially in the upper half of the liquid phase was revealed to be effective, supported in combination by a comparable discharge flow and a successful energy transmission.
