cylindricalInletVelocity

Description

The cylindricalInletVelocity is a velocity inlet boundary condition to model inlet velocity in cylindrical coordinates using a central axis, central point, revolutions per minute (rpm), axial and radial velocity magnitudes.

Usage

The condition requires entries in both the boundary and field files.

Boundary file

<patchName>
{
    type            patch;
    ...
}

Field file

<patchName>
{
    // Mandatory entries
    type            cylindricalInletVelocity;
    origin          <vector>;
    axis            <vector>;
    axialVelocity   <Function1<scalar>>;
    radialVelocity  <Function1<scalar>>;
    rpm             <Function1<scalar>>;

    // Inherited entries
    ...
}
