Class
|
||||
Foam::compressible::RASModels::mutkRoughWallFunctionFvPatchScalarField
|
||||
|
||||
Description
|
||||
Boundary condition for turbulent (dynamic) viscosity when using wall
|
||||
functions for rough walls.
|
||||
|
||||
Manipulates the E parameter to account for roughness effects, based on
|
||||
KsPlus.
|
||||
|
||||
- roughness height = sand-grain roughness (0 for smooth walls)
|
||||
- roughness constant = 0.5-1.0 (0.5 default)
|
||||
|
||||
Usage
|
||||
\table
|
||||
Property | Description | Required | Default value
|
||||
Ks | sand-grain roughness height | yes |
|
||||
Cs | roughness constant | yes |
|
||||
\endtable
|
||||
|
||||

|
||||
\verbatim
|
||||
<patchName>
|

type mutkRoughWallFunction;
|
||||
Ks uniform 0;
