• based on the inlet-outlet condition
  • sets the turbulent specific dissipation rate based on the patch turbulence kinetic energy and user-supplied mixing length
\[\omega_p = \frac{k^{0.5}}{C_{\mu}^{0.25} L}\]
  • in the event of reverse flow, a zeroGradient condition is applied, i.e.
\[\frac{d \omega}{d x} = 0\]


The condition is specified in the field file using:

    type            turbulentMixingLengthFrequencyInlet;
    mixingLength    1;
    value           <field value>;

    // Optional entries
    omega           omega;
    phi             phi;
