Spalart-Allmaras Improved Delayed Detached Eddy Simulation (IDDES)

Note
Under construction - please check again later

# 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 $$\tilde{d}$$:

$\tilde{d} = \max \left( \tilde{f_d} (1 + f_e) L_{RAS} + (1 - \tilde{f_d}) L_{LES}, SMALL \right)$

# Usage

The model is specified using:

LES
{
turbulence      on;
LESModel        SpalartAllmarasIDDES;
}


# Boundary conditions
