Class
    Foam::swirlInletVelocityFvPatchVectorField
 
Group
    grpInletBoundaryConditions
 
Description
    This boundary condition describes an inlet vector boundary condition in
    swirl coordinates 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.
