6.4.2 Setting Up the Shear-Stress Transport k-ω Model

If you choose the shear-stress transport k-ω model, the following options are available:

w Low-Re corrections
w Viscous heating (always activated for the density-based solvers)

6.5 Shear Flow Corrections

In the standard k-ω model, you also have the option of including corrections to improve the accuracy
in predicting free shear flows. The Shear Flow Corrections option under the k-omega Options is
enabled by default in the Viscous Model dialog box, as these corrections are included in the standard k-
ω model. When this option is enabled, ANSYS FLUENT will calculate fβ.
Including Pressure Gradient Effects

If the enhanced wall treatment is used, you may include the effects of pressure gradients by enabling
the Pressure Gradient Effects option under the Enhanced Wall Treatment Options.
