Workshop 2024

Wall-modeled LES Workshop on Smooth-Body Separation, part of the High-Fidelity CFD Verification Workshop

This workshop will be held at the AIAA Scitech meeting on Jan 6-7, 2024. It is part of the High-Fidelity CFD Verification Workshop.

Focus of the workshop

While there are many interesting and important aspects of LES, this particular workshop is focused on the application of LES to wall-bounded flows at very high Reynolds numbers. As is well known, this requires the turbulence in the inner part of the boundary layer to be modeled rather than resolved. 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).
The workshop will focus on 3 test cases, all chosen to strike a balance between physical realism and computational cost, where it is recognized that a limited computational cost implies both that a broader group of research groups can participate and (equally importantly) that participants can afford to compute on a sequence of refined grids in order to carefully assess grid convergence (or the lack thereof).
The purpose of the workshop is to provide a snapshot of the predictive capability of modern WMLES methods on smooth-body separation flows at high Reynolds numbers, to build a comparative database for use in future method assessments, and to advance our ability to perform verification of WMLES solvers.
