CFD Simulation of the Fluid Hydrodynamics in a Continuous Stirred-Tank Reactor
Continuous stirred-tank reactors (CSTR) are widely applied in the chemical, food, and pharmaceutical engineering fields. The micro-scale fluid dynamics are important for the optimal processing study since they have a dominating influence on the overall performance of the reactor. In this article, 3-dimensional Computational Fluid Dynamics (CFD) simulations are carried out to portray the flow ch...
متن کاملCFD 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...

متن کاملA 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 ...
متن کاملExperimental measurement and computational fluid dynamics simulation of mixing in a stirred tank: a review
Introduction Mixing in stirred tanks is driven by the impeller-generated convective motion at larger scales, by turbulent transfer at smaller scales and diffusion at molecular scales. Smith reported that the lack of a fundamental understanding of the processes in stirred vessels leads to losses in the order of US$10 billion per year due to non-optimal energy utilisation. Thus, there is a need t...
