This boundary condition provides a turbulent kinetic energy condition, based on user-supplied turbulence intensity, defined as a fraction of the mean velocity:
\[ k_p = 1.5 (I |U|)^2 \]
where
\( k_p \) | = | kinetic energy at the patch |
\( I \) | = | turbulence intensity |
\( U \) | = | velocity field |
In the event of reverse flow, a zero-gradient condition is applied.
Property | Description | Required | Default value |
---|---|---|---|
intensity | fraction of mean field [0-1] | yes | |
U | velocity field name | no | U |
phi | flux field name | no | phi |
Example of the boundary condition specification:
<patchName> { type turbulentIntensityKineticEnergyInlet; intensity 0.05; // 5% turbulence value uniform 1; // placeholder }
