DES Turbulence Model
 
3 Attachment(s)
Hi all,

I'm going to simulate flow over an ellipse with the k-omega-SST Improved Delayed Detached Eddy Simulation (IDDES) in openFoam.

I have created a mesh with snappyHexMesh and I use y+=1 to resolve the boundary layer.

However, I could not get reasionable results, I have attached Turbulent Kinetic Energy (K) and DES region for you. As you can see from K contour it is not on the wall!

Besides, DES region is devided in some irrelevant parts!

I would appreciate it if you help me in this matter.

I'm still interested in receiving your opinions.
Thank you.
