3D-CAD: Cyclone Separator

Cyclone separators provide a low-cost solution for removing particulate matter from gas or liquid flows. In Simcenter STAR-CCM+, the 3D-CAD geometry modeler provides all the tools necessary for creating this type of geometry directly.

In this tutorial you create a cyclone separator model based on the dimensions used by Stairmand in his experimental studies[reflink]. To permit parametric studies, all dimensions are created relative to the core cyclone diameter, D.

While creating the geometry in 3D-CAD, you set up a design parameter for the core diameter, D. Thereafter, you can set any diameter you wish by adjusting the parameter—and all other dimensions update accordingly.

The following basic concepts of 3D-CAD are introduced in this tutorial:

  • Creating a 3D-CAD model
  • Creating sketches and applying dimensions
  • Using the loft feature and extruding sketches
  • Setting up a design parameter
