Physical Reasoning of Double- to Single-Loop Transition in Industrial Reactors using Computational Fluid Dynamics [PDF]

Journal of Applied Fluid Mechanics, 2022
Double- to single-loop pattern transition and a significant reduction in the power number with a decrease in the clearance of the Rushton turbine impeller in a baffled reactor was elucidated in earlier research works.
