Hybrid Approach for Mixing Time Characterization and Scale-Up in Geometrical Nonsimilar Stirred Vessels Equipped with Eccentric Multi-Impeller Systems—An Industrial Perspective

Computational Flow Modelling of Dual Rushton Impeller Stirred Vessels

Flow in baffled stirred vessels involve interactions between flow around rotating impeller blades and stationary baffles. When more than one impeller is used, which is quite common in practice, the flow complexity is greatly increased, especially when there is an interaction between the multiple impellers. The extent of interaction depends on relative distances between the impellers and clearan...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

A hybrid method for simulation of axial ̄ow impeller driven mixing vessels

A hybrid method for the simulation of Reynolds-averaged turbulent ̄ows in axial ̄ow impeller driven mixing vessels is described. The time-mean ̄ow in the impeller region is modelled using blade element theory, while the ̄ow in the remainder of the vessel is simulated using a second-order ®nite-volume Reynolds-averaged numerical scheme. The two models are iteratively coupled through boundary con...

Compartment Mixing Model in a Stirred Tank Equipped Dual Rushton Turbine

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...
