k-ω-SST Delayed Detached Eddy Simulation (DDES)

Properties​

  • Two equation model for the turbulence kinetic energy, kk, and turbulence specific dissipation rate, ω\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 d~\tilde{d}:

Default model coefficients​

Initialisation​

Usage​

The model is specified using:

LES
{
    turbulence      on;
    LESModel        kOmegaSSTDDES;
}

Boundary conditions​

Inlet

Outlet

Walls

  • wall functions
