Rotation using standard rotatingWallVelocity

rotatingWallVelocity is boundary condition for boundary type wall. rotatingWallVelocity can be used only for rotating wall (patch) that have all faces parallel with the rotation trajectory. For example a cylinder rotating around its axis can have rotatingWallVelocity.

File 0/rotor/U for turbine rotor may have following patch:

 

".*_cylinder"
    {
        type            rotatingWallVelocity;
        origin          (0 0 0);
        axis            (0 0 1);
        omega          -62.8; // 600 RPM,   (RPM/60)*2*PI=rPs
    }
