Abstract

Abstract In the first part of the review, published literature regarding the CFD modelling of single‐phase turbulent flow in stirred tank reactors with radial flow impellers was critically analysed. A brief overview of different turbulence models (standard k − ε model, RNG k − ε model, the Reynolds stress model and large eddy simulation) as well as impeller baffle interaction models has been presented in the previous part. This part is concerned with the review of literature regarding CFD simulation of axial flow impellers. Comprehensive simulations have been carried out using various turbulence models and the model predictions (of all the mean velocities, turbulent kinetic energy and its dissipation rate) have been compared with the experimental measurements at various locations in the tank. The strengths and weaknesses of various turbulence models for axial flow impellers is presented. The quantitative comparison of exact and modelled turbulence production, transport and dissipation terms has highlighted the reasons behind the partial success of various modifications of standard k − ε model as well as Reynolds stress model. Literature efforts on multiple impeller systems and multiphase systems have been discussed in a separate section. Based on these results, suggestions have been made for the future work in this area.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The predictive power of a CFD model depends decisively on the selection of the considered phenomena as well as on the selected modeling approach and the concrete submodels.

    “However, the predictive power of a CFD model depends decisively on the selection of the considered phenomena as well as on the selected modeling approach and the concrete submodels [46-48].”
  • The sliding mesh technique is routinely used for the simulation of stirred tanks or other geometries with rotating parts.

    “The technique is also routinely used for the simulation of stirred tanks or other geometries with rotating parts [47,48,134].”
  • For stirred tank reactors, the numerical technique used to capture the motion of rotating agitators and the choice of a turbulence model significantly affect the computed flow fields.

    “This lack of knowledge should be closed since it was demonstrated for stirred tank reactors that the numerical technique being used to capture the motion of rotating agitators and the choice of a turbulence model significantly affect the computed flow fields [47,48].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
