Mixing Characteristics in a Continuous Stirred Vessel-Analysis by Impulse Testing Method

Review on Gas-liquid Mixing Analysis in Multiscale Stirred Vessel Using Cfd

The liquid-gas operations in the stirred vessels can be a complex system to analyze because of the presence numerous parameters and operational conditions that effect its performance. Since the past decades, CFD analysis is gaining popularity and even replacing the need for extensive experimentation. The objective of this review is to establish the approaches and equations commonly used in CFD ...

Solvent Extraction of Rare Earth Metal by a Continuous Stirred Vessel

The solvent extraction of neodymium, a rare earth metal, was studied with a continuous stirred vessel. One of the widely used extractants, 2-ethylhexyl phosphonic acid mono-2-ethylhexyl ester (PC-88A), diluted with kerosene was selected as an extracting organic solvent. First, the extraction equilibrium of neodymium between aqueous and organic phases was measured in a batch-wise experimental ru...

A Study on Liquid-liquid Mixing in a Stirred Tank with a 6-Blade Rushton Turbine

The turbulent flow field generated in a baffled stirred tank was computed by large eddy simulation (LED) and the flow field was developed using the Sliding Mesh (SM) approach. In this CFD study, mixing times and power number have been determined for a vessel agitated by a 6-blade Rushton turbine. The predicted results were compared with the published experimental data. The satisfactory results ...

Flow characteristics of gas-liquid-particle mixing in a gas-stirred ladle system with throughflow

An experimental study is performed on air-liquid-particle mixing, resulting from an air-particle mixture injected into a liquid flowing through a slender ladle. Flow visualization combined with image processing is employed to investigate the bubble and particle behavior at the nozzle outlet. Effort is directed to particle discrimination in both the liquid and the bubbles to determine particle d...
