Properties🔗
- One equation model based on a modified turbulence viscosity, \(\tilde{\nu}\)
Model equations🔗
The model equations are the same as used by the DES variant of the model, with a different approximation for \(\tilde{d}\):
\[\tilde{d} = \max \left( \tilde{f_d} (1 + f_e) L_{RAS} + (1 - \tilde{f_d}) L_{LES}, SMALL \right)\]Default model coefficients🔗
