Abstract
AbstractThe development of a multi‐impeller reactor for the mixing of non‐Newtonian fluids under full flow regime conditions depends on mixing time, power consumption, and mixing energy. These parameters must be well‐defined with 3‐blade propellers, 4‐pitched turbines, and 6‐flat‐blade turbines. An innovative expression of mixing time for the thermal pulse disturbance method is introduced. The Buckingham's π‐theorem was utilized to denominate and transfer dimensionless power and homogenization number. To achieve consistent mixing, the results indicated that axial flow of the 4‐pitched‐blade turbine is the most effective approach. The examined correlation is a functional tool to determine the mixing energy based on the measured specific power consumption and mixing time.
