This source condition provides a turbulent kinetic energy based on user-supplied turbulence intensity, defined as a fraction of the mean velocity:
where
= | kinetic energy values | |
= | turbulence intensity | |
= | velocity field |
In the case of a sink, the current cell values are used instead.
Property | Description | Required | Default value |
---|---|---|---|
intensity | fraction of mean field [0-1] | yes | |
U | velocity field name | no | U |
Example of the boundary condition specification:
<patchName> { type turbulentIntensityKineticEnergyInlet; intensity 0.05; // 5% turbulence }
