Hairpin vortices

Hairpin vortices


In this tutorial, we will simulate hairpin vortices behind a hemisphere. This case (which seems to be a simple one), can be rather tricky and requires the use of some tricks to trigger the hairpin vortices using coarse meshes. You will learn about,

  • Understanding the physics
  • Case setup and workflow
  • Meshing
  • Running the simulation
    • Steady-state
    • Transient
  • Sampling and plotting
  • Mesh refinement


You can download the case files at this link.
