Two-equation eddy-viscosity turbulence models for engineering applications

Menter, F. R.·1994·AIAA Journal

Abstract

Two new two-equation eddy-viscosity turbulence models will be presented.They combine different elements of existing models that are considered superior to their alternatives.The first model, referred to as the baseline (BSL) model, utilizes the original k-u model of Wilcox in the inner region of the boundary layer and switches to the standard A>e model in the outer region and in free shear flows.It has a performance similar to the Wilcox model, but avoids that model's strong freestream sensitivity.The second model results from a modification to the definition of the eddy-viscosity in the BSL model, which accounts for the effect of the transport of the principal turbulent shear stress.The new model is called the shear-stress transport-model and leads to major improvements in the prediction of adverse pressure gradient flows.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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 most significant advantage of the k-w formulation is that it does not involve damping functions like the k-# model, thereby being numerically more robust and simplifying implementation of boundary conditions.

    “Most probably the most significant advantage of the k -w formulation is that it does not involve damping functions like the k -# model, thereby being numerically more robust and simplifying the implementation of boundary conditions [227].”
  • Turbulent viscosity is highly dependent on the value of w specified outside the boundary layer, such as at the inlet.

    “The turbulent viscosity is highly depending on the value of w specified outside of the boundary layer, like, for instance at the inlet [227].”

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.
