Class
    Foam::cylindricalInletVelocityFvPatchVectorField
 
Group
    grpInletBoundaryConditions
 
Description
    This boundary condition describes an inlet vector boundary condition in
    cylindrical coordinates given a central axis, central point, rpm, axial
    and radial velocity.
 
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  |
        rpm          | rotational speed (revolutions per minute) | yes|
    \endtable
 
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            cylindricalInletVelocity;
        axis            (0 0 1);
        origin          (0 0 0);
        axialVelocity   constant 30;
        radialVelocity  constant -10;
        rpm             constant 100;
    }
    \endverbatim
 
Note
    The \c axialVelocity, \c radialVelocity and \c rpm entries are Function1
    types, able to describe time varying functions.  The example above gives
    the usage for supplying constant values.
