30 Description
31  This boundary condition provides a turbulence specific dissipation,
32  \f$\omega\f$ (omega) inlet condition based on a specified mixing length.
33  The patch values are calculated using:
34 
35  \f[
36  \omega_p = \frac{k^{0.5}}{C_{\mu}^{0.25} L}
37  \f]
38 
39  where
40 
41  \vartable
42  \omega_p | patch omega values
43  C_{\mu} | Model coefficient, set to 0.09
44  k | turbulence kinetic energy
45  L | length scale
46  \endvartable
47 
48 Usage
49  \table
50  Property | Description | Required | Default value
51  mixingLength | Length scale [m] | yes |
52  phi | flux field name | no | phi
53  k | turbulence kinetic energy field name | no | k
54  \endtable
55 
56  Example of the boundary condition specification:
57  \verbatim
58  <patchName>
59  {
60  type turbulentMixingLengthFrequencyInlet;
61  mixingLength 0.005;
62  value uniform 200; // placeholder
63  }
64  \endverbatim
65 
66 Note
67  In the event of reverse flow, a zero-gradient condition is applied
