Defining a Blower Component

You can apply properties to a 3D part that model the behavior of a blower. The blower component you define expels fluid radially.

When you define a blower component in one finite element model (FEM) representation, the app defines it in all FEM representation instances.

Before you begin:
  1. Create a cylindrical geometry to represent the abstracted version of the blower, instead of using the detailed blower geometry.

    For more information, see Creating Abstraction Shapes.

  2. Mesh the blower geometry.
  3. Add the blower geometry to the simulation.

About Blower Components
  1. From the E-Cooling section of the action bar, click Blower Component .
  2. Optional: Enter a descriptive Name.
  3. From the 3D area, select a cylindrical part to be the blower.
    A yellow glyph, which represents the blower's blades, appears in the 3D area. A yellow arrow indicates the direction in which the blades rotate.
  4. From the 3D area, select an Inlet surface to indicate where the flow enters the blower.
  5. From the 3D area, select an Outlet surface to indicate where the flow exits the blower.
  6. Enter a value for the Blade angle, which is the angle of the blower's blades.
    If you enter a nonzero blade angle, the yellow glyph changes to show curved blades.
  7. Select the axis system and the axis about which the blades rotate.
    OptionDescription
    Global Aligns the local feature triad with the global coordinate system.
    Local Aligns the local feature triad with a selected axis system in the model.
  8. Enter a value for the Fan hub radius, which is the radius of the housing that covers the center of the impeller.
  9. Add a fan curve to dynamically change the intake of flow into the blower.
    1. From the Fan curves section, click Add a fan curve .
      The Fan Curve dialog box appears.
    2. Enter a value for the RPM, which is the impeller's revolutions per minute (RPM).
    3. In the table, enter data points for the Volume Flow Rate and the Pressure Jump to define the relationship between the volume flow rate and pressure rise for a constant RPM.
    4. Click OK.
  10. Click OK.
    The yellow glyph turns blue to indicate that you created the blower component.
