Properties🔗

• Two equation model for the turbulence kinetic energy, \(k\), and turbulence specific dissipation rate, \(\omega\).
• Based on the k-omega SST model

Model equations🔗

The model equations are the same as used by the DES variant of the model, with a different approximation for \(\tilde{d}\):

Default model coefficients🔗

Initialisation🔗

Usage🔗

The model is specified using:

LES
{
    turbulence      on;
    LESModel        kOmegaSSTIDDES;
}

Boundary conditions🔗

Inlet

• fixedValue

Outlet

• Constrained outlet

Walls

• wall functions
