Particle-resolved PIV experiments of solid-liquid mixing in a turbulent stirred tank

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 ...

CFD Modeling of Gas-Liquid Hydrodynamics in a Stirred Tank Reactor

Multiphase impeller stirred tank reactors enhance mixing of reacting species used in a variety of chemical industries. These reactors have been studied based on Computational Fluid Dynamics (CFD) that can be used in the analysis, design and scale up of these reactors. Most of the researches done in this area are limited to single phase reactors, and a few remaining two phase flow investigat...

Gas-liquid-solid Operation of a Vortex-ingesting Stirred Tank Reactor

The vortex-ingesting stirred tank reactor uses a combination of a helical screw impeller and concentric draft-tube to entrain and recycle headspace gas and disperse it as bubbles in a liquid reaction solvent. This study presents an experimental characterisation of a 0.29 m diameter vortex-ingesting gas-liquid stirred reactor, operated with solids mass fractions from 0 to 25%, over a range of sp...
