12.13.9 Shear Flow Corrections

In the standard $k$- $\omega$ 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 $k$- $\omega$ model [ 94]. When this option is enabled, ANSYS FLUENT will calculate $f^*_{\beta}$ using this equation (in the separate Theory Guide) and $f_{\beta}$ using this equation (in the separate Theory Guide). If this option is disabled, $f^*_{\beta}$ and $f_{\beta}$ will be set equal to 1.
