12.11.2 Setting Up the Realizable $k$- $\epsilon$ DES Model

For the Realizable $k$- $\epsilon$ submodel, the model-specific options are

• delayed DES (Section  12.13.4)

• viscous heating (always activated for the density-based solvers) (Section  12.13.1)

The model constant $C_{\rm des}$ is set to 0.61 for the Realizable $k$- $\epsilon$ model (see this section in the separate Theory Guide).
