AIAA CFD High Lift Prediction Workshop (HLPW-4)
by the AIAA Applied Aerodynamics Technical Committee
This workshop has concluded. It
was an all-day meeting held on Friday, January 7, 2022,
in San Diego CA (associated with
AIAA SciTech 2022).
- Test cases were on the
High Lift version of the Common Research Model (CRM-HL).
- Please sign up (see the AIAA HLPW Committee's CONTACT info below) to be kept informed about future
Goals of the Workshop Series
- Assess the numerical prediction capability (meshing, numerics, turbulence
modeling, high-performance computing requirements, etc.) of current-generation CFD
technology/codes for swept, medium-to-high-aspect ratio wings for landing/take-off
- Develop practical modeling guidelines for CFD prediction of high-lift
- Determine the elements of high-lift flow physics that are critical for
modeling to enable the development of more accurate prediction methods and tools.
- Enhance CFD prediction capability for practical high-lift
aerodynamic design and optimization.
- HLPW makes use of configurations for which the geometry and measured data are fully
open (with unrestricted public availability), forming the basis for international
cooperation/collaboration on this important open topic. In keeping with the goals
of the HLPW series, CFD data generated by workshop participants are also made publicly
available. However, note that accuracy and adequacy of participant results are not
guaranteed. All participant CFD results should be viewed as workshop-type solutions,
for the purpose of advancing the shared understanding of the high-lift community,
and not as final production-type solutions.
- This workshop was held concurrently with
the Geometry and Mesh Generation Workshop
as a combined HLPW-4/GMGW-3 workshop.
- This workshop was conducted differently than the HLPWs of the past. This time,
it included collaborative efforts during the months leading up to the
workshop to answer key questions of importance to both the mesh generation and
high lift aerodynamics communities. These collaborative efforts were
accomplished through "Technology Focus Groups" (TFGs).
- When participating in the workshops, participants could choose to be either an active participant or an
- We asked all active participants to join at least one TFG,
in order to be engaged in workshop-related
collaborative research activities during the months prior to the workshops. The TFGs covered
specific areas of interest that spanned both workshops.
These areas were:
- Geometry Modeling and Preparation for Meshing
- Fixed Grid RANS (meshing and CFD)
- Mesh Adaptation for RANS (meshing and CFD)
- High Order Discretization (meshing and CFD)
- Hybrid RANS/LES (meshing and CFD)
- Wall-Modeled LES and Lattice-Boltzmann (meshing and CFD)
- People who did not choose (or were unable) to be members of any TFG could still perform research
on their own (or do nothing) and attend the workshops as an observer, but their work was not shown
or represented at the workshops.
- The list of TFGs and their members can be found below in the "TFG List and Associated
