Abstract
The mixing pattern and power number in a stirred vessel depend not only on the impeller design but also on the impeller/tank geometry and flow regime. The relationship between these parameters is reported for a Rushton turbine (6DT), six-bladed 45°-pitched turbine pumping down (6MFD) and (6MFU) up and three proprietary impellers. The impellers were used over a wide range of impeller diameter (D)/vessel diameter (T) and impeller clearance (C)/T values. Flow patterns were recorded and power numbers were measured as a function of Reynolds number from about 40 to about 50,000 in Newtonian fluids. The results obtained were used to aid in the study of the impellers in solid-liquid and three-phase systems.
