Creating a Streamlines Scene

Create a scene to display the streamlines inside the cyclone separator.

  1. Create a Geometry Scene.
  2. Switch to the Scene/Plot tree and rename the Geometry Scene 2 node to Streamlines.

Streamlines are created as a derived part. In this case, the streamlines are tracked from the cyclone inlet.

  1. Switch to the Simulation tree and create a streamline derived part as follows:
    1. Right-click the Derived Parts node and select New > Streamline.
    2. In the Create Streamline panel, set the following properties:
      Property Setting
      Input Parts Select Regions > Main Body and Outlet Pipe
      Seed Parts Regions > Main Body > Boundaries > Inlet
      Part U-Resolution 2
      Part V-Resolution 8
      Display New Streamline Displayer
    3. Click Create and Close.
Define the scene settings:
  1. Click Scene/Plot.
  2. Select the Streamlines > Surface 1 node and set Opacity to 0.3.
Adjust the appearance of the streamlines to display ribbons instead of the default lines:
  1. Select the Streamlines > Streamlines Stream 1 node and set Mode to Ribbons.
Adjust the scalar field of the streamlines to display velocity:
  1. Select the Streamline Stream 1 > Scalar Field node.
  2. Set Function to Velocity > Lab Reference Frame > Magnitude.
To animate the streamlines:
  1. Set the following properties:
    Node Property Setting
    Streamlines
    Streamline Stream 1 > Animations Animation Mode Tracers
    Streamline Settings Delay between tracers (sec) 6
    Head size 0.01
    Tail Length (sec) 1

To extend the streamlines through the fluid domain up to the outlet, increase the maximum propagation property. This property defines how far the streamlines are propagated through the fluid domain from the starting points.

  1. Select the Derived Parts > Streamline > 2nd Order Integrator node and set Maximum Propagation to 15.
    The streamlines appear as follows:

  2. In the Animation toolbar:
    1. Click (Play)
    2. To stop the animation, click (Stop)
  3. Save the simulation.
