<patchName> { // Mandatory entries (unmodifiable) type kLowReWallFunction; // Optional entries (unmodifiable) Ceps2 1.9; Ck -0.416; Bk 8.366; C 11.0; // Optional (inherited) entries ... }
where the entries mean:
Property | Description | Type | Req'd | Dflt |
---|---|---|---|---|
type | Type name: kLowReWallFunction | word | yes | - |
Ceps2 | Model coefficient | scalar | no | 1.9 |
Ck | Model coefficient | scalar | no | -0.416 |
Bk | Model coefficient | scalar | no | 8.366 |
C | Model coefficient | scalar | no | 11.0 |
The inherited entries are elaborated in:
Viscous and inertial sublayer predictions for k
are blended in a stepwise manner:
\[ k = k_{log} \qquad if \quad y^+ > y^+_{lam} \]
\[ k = k_{vis} \qquad if \quad y^+ <= y^+_{lam} \]
where
\( k_{vis} \) | = | k prediction in the viscous sublayer |
\( k_{log} \) | = | k prediction in the inertial sublayer |
\( y^+ \) | = | estimated wall-normal height of the cell centre in wall units |
\( y^+_{lam} \) | = | estimated intersection of the viscous and inertial sublayers |
Cmu

, and E
