atmNutSource
adds/subtracts a given artificial turbulent viscosity field to/from nut
for atmospheric boundary layer modelling.atmNutSource
can be applied on any RAS turbulence model.atmNutSource
inherits the traits of the fvOption, and cellSetOption
.Corrections applied to:
nut | Turbulent viscosity [m2/s]
Required fields:
nut | Turbulent viscosity [m2/s] artNut | Artificial turbulent viscosity [m2/s]
The model expression:
\[ \nu_t += \nu_{t_{art}} \]
where
\( \nu_t \) | = | Turbulent viscosity [m2/s] |
\( \nu_{t_{art}} \) | = | Artificial turbulent viscosity [m2/s] |

atmNutSource1 { // Mandatory entries (unmodifiable) type atmNutSource; atmNutSourceCoeffs { // Mandatory (inherited) entries (unmodifiable) selectionMode all; // Optional entries (unmodifiable) nut artNut; } // Optional (inherited) entries ... }
where the entries mean:
Property | Description | Type | Required | Default |
