Properties🔗

• Incompressible only
• Two-equation model

Model equations🔗

The turbulence kinetic energy equation is given by:

\[\Ddt{k} = \div \left( D_k \grad k \right) + G - \epsilon\]

and the turbulence dissipation rate equation by:

\[\Ddt{\epsilon} = \div \left( D_\epsilon \grad \epsilon \right) + C_{\epsilon 1} G \frac{\epsilon}{k} - C_{\epsilon 2} f_2 {\epsilon^2}{k} + E\]

Default model coefficients🔗

Usage🔗

The model is specified using:

RAS
{
    turbulence      on;
    RASModel        LienCubicKE;
}
