The test case will be run at Mach 0.2 in order to enable both compressible and incompressible codes to be used.

Therefore, the workshop will focus on a central test case that features an equilibrium incoming boundary layer, separation over a smoothly curved ramp, and reattachment. One of the most important challenges in such “wall-modeled LES” is the ability to accurately predict separated flows, specifically flows where the separation is not dictated by abrupt geometric changes (e.g., sharp corners). As is well known, this requires the turbulence in the inner part of the boundary layer to be modeled rather than resolved. While there are many interesting and important aspects of LES, the organizing committee has decided to focus this specific workshop on the application of LES to wall-bounded flows at very high Reynolds numbers. A flyer for the workshop can be downloaded here. The workshop will be held during the weekend immediately following the SciTech meeting, specifically on Sat/Sun January 8-9, 2022.

The AIAA Fluid Dynamics Technical Committee’s LES Discussion Group is organizing a workshop focused on the prediction of a separated flow using wall-resolved LES (WRLES) and wall-modeled LES (WMLES) at the SciTech 2022 meeting in San Diego, CA.
