Step 5: Cell Zone Conditions

Cell Zone Conditions

1.   Define the boundary conditions for the rotational reference frame ( fluid-13).

Cell Zone Conditions fluid-13 Edit...

(a)   Retain the Rotation-Axis Origin default setting of (0,0).

  This is the center of curvature for the circular boundaries of the rotating zone.

(b)   Select Moving Reference Frame from the Motion Type drop-down list.

(c)   Enter 261 rad/s for Speed in the Rotational Velocity group box.

  Scroll down to find the Speed number-entry box.

(d)   Click OK to close the Fluid dialog box.

Note:   Since the other fluid zones are stationary, you do not need to set any boundary conditions for them. If one of the remaining fluid zones was also rotating, you would need to set the appropriate rotational speed for it.
