Finding point of flow separation

Using SimScale Post-processing
1

Which parameter should I see in CFD post process to find the separation point of an airfoil at high angle of attack?

Hey there, and thanks for using the forum!

Here are some ideas on how to visualize the flow separation:

  • Create a particle trace from the leading edge, and visualize where the traces separate from the body.
  • Color the surface by wall shear stress in the direction of flow, so you get negative values in the separation regions. For this one you need to request the wall shear stress field under Result Control.
  • Create iso-surface on total pressure, with a threshold that allows you to identify regions of low pressure.

If you share the project URL, we could be able to help you test the options.
