Creating the Cyclone Body

Create the main body and conical section of the cyclone separator geometry.

  1. Create a sketch for the main body of the cyclone geometry:
    1. Right-click the XY node and select Create Sketch.
    2. In the Sketch panel, click (View Normal to Sketch Plane).
    3. To specify the distance between the grid lines on the sketch plane, click (Set Sketch Grid Spacing).
    4. In the Grid Spacing dialog, set Grid Spacing to 0.1 m.
    5. Click OK.
      After setting the spacing, zoom out until you can see the full circle of the outlet pipe.
    6. Click (Create Circle) and draw a circle centered on the origin (0,0).
    7. Right-click the edge of the circle and select Apply Radius Dimension.
    8. In the Dimension dialog, enter 0.5*$D and click OK.
    9. In the Sketch panel, click OK.
    10. In the feature tree, rename Sketch 1 to Main Body Sketch.
  2. To form the main body, extrude the sketch:
    1. Right-click the Main Body Sketch node and select Extrude.
    2. In the Extrude panel, set Distance to 1.5*$D.
    3. Set Body Interaction to None.
    4. In the Extrude panel, click OK.
    5. Within the Body Groups node, rename Body 2 to Main Body.
  3. To remove the volume occupied by the outlet pipe:
    1. Under Body Groups, right-click the Main Body node and select Boolean > Subtract .
    2. In the Subtract Bodies panel, to the right of the Tool Bodies selection box, click (Open Selector).
    3. Within the Select Tool Bodies panel, select Outlet Pipe. Click (Close Selector).
    4. In the Subtract Bodies panel, activate the two options, Keep Tool Bodies and Imprint.


    5. Click OK.
For the conical section of the cyclone separator you prepare two sketches and then apply a loft feature between them.
  1. Extract the sketch from the bottom face of the main body part:
    1. In the Vis toolbar, click (Make Scene Transparent).
    2. In the graphics window, select the bottom face of the main body part:


    3. Right-click on the face and select Create Sketch > From Face Edges .
    4. In the Sketch panel, click OK.
  2. Create a plane on which to sketch the base of the cyclone:
    1. Right-click the XY node and select Reference Geometry > Plane by Transformation.
    2. In the Plane By Transformation panel, click OK.
    3. Select the Plane 1 node and in the Properties window enter 4*$D for the Z component of the Translation Vector.
    4. Rename Plane 1 to Cyclone Base Plane.
    5. At the bottom of the 3D-CAD panel, click Update3D-CAD .
  3. Draw the cyclone base:
    1. Right-click on the Cyclone Base Plane node and select Create Sketch.
    2. In the Sketch panel, click (View Normal to Sketch Plane).
    3. Click (Create Circle) and draw a circle around the origin.
    4. Right-click on the circle and select Apply Radius Dimension.
    5. In the Dimension dialog, enter 0.18*$D and click OK.
    6. In the Sketch panel, click OK.
    7. In the feature tree, rename the Sketch 1 node to Cyclone Base Sketch.
  4. Create the body of the conical section using the loft feature:
    1. Select the Cyclone Base Sketch node, press and hold <CTRL>, and also select the FaceSketch 1 node.
    2. Right-click one of the nodes and select Loft.
    3. In the Loft panel, click OK.
    4. Rename Loft 1 to Conical Section Loft.
The main body and conical section are created for the cyclone separator geometry.
