Lien cubic k-epsilon

Note
Under construction - please check again later

# 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:

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

# Usage

The model is specified using:

RAS
{
turbulence      on;
RASModel        LienCubicKE;
}
