Class
|
||||
Foam::swirlInletVelocityFvPatchVectorField
|
||||
|
||||
Description
|
||||
This boundary condition describes an inlet vector boundary condition in
|
||||
swirl co-ordinates given a central axis, central point, axial, radial and
|
||||
tangential velocity profiles.
|
||||
|
||||
Usage
|
||||
\table
|
||||
Property | Description | Required | Default value
|
||||
axis | Axis of rotation | yes |
|
||||
origin |Origin of rotation | yes |
|
||||
axialVelocity | Axial velocity profile [m/s] | yes |
|
||||
radialVelocity | Radial velocity profile [m/s] | yes |
|
||||
tangentialVelocity | tangential velocity profile [m/s] | yes |
|
||||
\endtable
|
||||
|
||||
Example of the boundary condition specification:
|
||||
\verbatim
|
||||
<patchName>
|
||||
{
|
||||
type swirlInletVelocity;
|
||||
axis (0 0 1);
|
||||
origin (0 0 0);
|
||||
axialVelocity constant 30;
|
||||
radialVelocity constant 10;
|
||||
tangentialVelocity constant 100;
|
||||
}
|
||||
\endverbatim
|
||||
|
||||
Note
|
||||
The \c axialVelocity, \c radialVelocity and \c tangentialVelocity entries
|
||||
are Function1 types, able to describe time varying functions. The example
|
||||
above gives the usage for supplying constant values.
