Detailed Description

This boundary condition provides a turbulence specific dissipation, $\omega$ (omega) inlet condition based on a specified mixing length. The patch values are calculated using:

\[ \omega_p = \frac{k^{0.5}}{C_{\mu}^{0.25} L} \]

where

$ \omega_p $ = patch omega values
$ C_{\mu} $ = Model coefficient, set to 0.09
$ k $ = turbulence kinetic energy
$ L $ = length scale
Usage
Property Description Required Default value
mixingLength Length scale [m] yes
phi flux field name no phi
k turbulence kinetic energy field name no k

Example of the boundary condition specification: 

    <patchName>
    {
        type            turbulentMixingLengthFrequencyInlet;
        mixingLength    0.005;
        value           uniform 200;   // placeholder
    }
Note
In the event of reverse flow, a zero-gradient condition is applied
