If you want to model
the flow in the coordinate system rotating with the rotating equipment,
you can enable the Rotation option.
Restrictions and Limitations
Note that the Rotation option
is incompatible with the High
Mach number flow option.
Procedure
- In the Wizard or General Settings on
the Analysis Type tab,
select the Rotation check box.
- Select an appropriate Type of rotation:
Global
rotating. With this option the model and the global
coordinate system are considered rotating with specified angular
velocity. So it is applicable when all non-rotating model components
are axisymmetrical with respect to the selected rotation axis. See “Global rotating” for details.
Local
region(s) (Averaging). This option allows to simulate
fluid flows in regions surrounding rotating solids, which are not bodies
of revolution by specifying multiple local rotating reference frame
within the model in cases where the rotor-stator interaction is
weak. See “Local region(s) (Averaging)” for details.
Local
region(s) (Sliding). This option allows to simulate
fluid flows in regions surrounding rotating solids, which are not
bodies of revolution by specifying multiple local rotating coordinate
systems within the model in cases where the rotor-stator interaction
is strong. See “Local region(s) (Sliding)” for details.
- If you have selected the Global rotating option:
- Click
and in the Rotation Axis dialog
box specify the rotational axis.
- Specify an Angular
Velocity value (ω)
which obeys the right-handle rule.
