Class
Foam::swirlInletVelocityFvPatchVectorField
Group
grpInletBoundaryConditions
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.
