AIAA CFD High Lift Prediction Workshop (HLPW-4)
by the AIAA Applied Aerodynamics Technical Committee
When: all-day meeting on Friday, January 7, 2022,
in San Diego CA (associated with
AIAA SciTech 2022).
Leading up to the workshop, a
Workshop Progress Meeting (virtual format) was held July 15-16, 2021. This meeting brought together all of the Technology Focus Groups
for an assessment of progress and determination of areas requiring more focus prior to the January in-person event.
Copies of the presentations are available below.
Any results or conclusions shown in the presentations are unofficial and PRELIMINARY ONLY; they are not published or publishable, and should not
be taken out of the context of a working team progress meeting. Similarly, many of the individual results are preliminary: they may be unconverged,
exploratory, or on grids that are too coarse. They should only be viewed as intended to help guide collective improvements of the
TFGs moving forward.
- Test cases will be on the
High Lift version of the Common Research Model (CRM-HL).
- Please sign up (see CONTACT info below) to be kept informed.
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.
- Like our last workshop (HiLiftPW-3), this workshop will be held concurrently with
the Geometry and Mesh Generation Workshop
(GMGW-3). Workshop participants
will be able to register for either workshop and attend sessions for both.
- These workshops will be conducted differently than in the past. This time,
they will include collaborative efforts during the months leading up to the
workshops to answer key questions of importance to both the mesh generation and
high lift aerodynamics communities. These collaborative efforts will be
accomplished through "Technology Focus Groups" (TFGs).
- When participating in the workshops, you can choose to be either an active participant or an
- We are asking 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 cover
specific areas of interest that span both workshops.
These areas are:
- 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)
- If you do not choose (or are unable) to be member of any TFG, then you may still perform research
on your own (or do nothing) and attend the workshops as an observer, but your work will not be shown
or represented at the workshops.
- Membership on a TFG implies active engagement.
- The current list of TFGs and their members can be found below in the "TFG List and Associated

*The virtual Workshop Progress Meeting (5 hours total) will be held Thursday July 15 from 4pm - 7pm eastern, and
on Friday July 16 from 8am - 10am eastern. (These times were chosen in an attempt to optimize attendance across many different
time zones where a majority of the participants are located.) There is no fee to attend, and there is not anticipated to
be any pre-registration required. The link connection information will be emailed to participants and others on the
HLPW mailing list around June 30.
**AIAA will charge a registration fee to attend the HLPW-4 workshop.
