k-omega-SST Improved Delayed Detached Eddy Simulation (IDDES)

Note
Under construction - please check again later

# 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 $$\tilde{d}$$:

# Usage

The model is specified using:

LES
{
turbulence      on;
LESModel        kOmegaSSTIDDES;
}


# Boundary conditions

Inlet

Outlet

Walls

• wall functions
