Mixing in gas-liquid contactors agitated by multiple turbines

JMT Vasconcelos, SS Alves, JM Barata - Chemical engineering science, 1995 - Elsevier
Liquid hydrodynamics in multiple-turbine aerated tanks was modelled in the loading regime
by the compartments-in-series model with back flow streams. Back flows between …

Intervortex mixing rates in high-viscosity liquids agitated by high-speed dual impellers

R Kuboi, AW Nienow - Chemical engineering science, 1986 - Elsevier
By using suitable flow visualization, photographs of flow patterns have been obtained for
high-viscosity Newtonian and shear-thinning non-Newtonian fluids with and without a yield …

Transitional mixing in multiple-turbine agitated tanks

JMT Vasconcelos, JM Barata, SS Alves - The Chemical Engineering …, 1996 - Elsevier
Blending of viscous newtonian liquids was studied in dual-and triple-turbine agitated tanks.
The dimensionless power, mixing and interstage flow numbers were all found to be …

Single‐particle approach for analyzing flow systems. Part II: Regional residence times and local flow rates

M Rubinovitch, U Mann - AIChE Journal, 1983 - Wiley Online Library
The analysis of Part I (Rubinovitch and Mann, 1983) is continued here, considering the

A single particle approach for analyzing flow systems. Part III: Multiple fluids

M Rubinovitch, U Mann - AIChE journal, 1985 - Wiley Online Library
This paper provides a stochastic model for general flow systems with several inlets and
outlets, where different fluids are fed through the various inlets. Several process …
