Description🔗
The turbulentMixingLengthFrequencyInlet
is a boundary condition that
provides a turbulence specific dissipation, omega
inlet condition based on
a specified mixing length. The patch values are calculated using:
where:
Property | Description |
---|---|
\(\omega_p\) | Patch omega values [1/s] |
\(C_\mu\) | Empirical model constant retrived from turbulence model |
\(k\) | Turbulent kinetic energy [m^2/s^2] |
\(L\) | Mixing length scale [m] |
Usage🔗
The condition requires entries in both the boundary and field files.
Boundary file🔗
<patchName>
{
type patch;

}
Field file🔗
<patchName>
{
// Mandatory entries
type turbulentMixingLengthFrequencyInlet;
mixingLength <scalar>;
// Optional entries
k <word>;
phi <word>;
// Inherited entries
...
}
where:
Property | Description | Type | Required | Default |
---|---|---|---|---|
type |
Type name: turbulentMixingLengthFrequencyInlet
|
word | yes | - |
mixingLength |
Mixing length scale [m] | scalar | yes | - |
phi |
Name of flux field | word | no | phi |
k |
Name of turbulent kinetic energy field | word | no | k |
The inherited entries are elaborated in:
