The

5th AIAA CFD High Lift Prediction Workshop (HLPW-5)

Sponsored by the AIAA Applied Aerodynamics Technical Committee

Overview

• HLPW-5 is a continuation in the series of High Lift Prediction Workshops.
• HLPW-4 was held in January 2022; you can find details at: https://hiliftpw.larc.nasa.gov/index-workshop4.html. There are also sites describing earlier HLPWs.
• Test cases for HLPW-5 will again involve the High Lift version of the Common Research Model (CRM-HL).
• This configuration (and all data associated with it) is open and in the public domain (see AIAA Paper 2020-2771 (Lacy & Clark)).
• At this time, anyone interested in the workshop should be a part of one of the Technology Focus Groups (TFGs), either as an active participant or observer. If you are not, please do so as soon as possible, by contacting a TFG leader. See HLPW5_KickoffMeeting_final4.pdf for more details, particularly page 11 (note: some of the information in the slides is preliminary and may have changed or may change in the future).
• If you are only interested in occasional general HLPW-5 announcements, then sign up to be included on the HiLiftPW email distribution list (see below).

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 (high-lift) configurations.
• Develop practical modeling guidelines for CFD prediction of high-lift flow fields.
• 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.

Important Information:

• 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 is being conducted in a similar way to HLPW-4, with virtual collaboration during the months leading up to the workshop. These collaborative efforts are accomplished through "Technology Focus Groups" (TFGs). The TFGs cover specific areas of interest: Fixed Grid RANS, Mesh Adaptation, High Order Discretization, Wall-Modeled LES, and Hybrid RANS/LES. More details can be found in the "TFG Details" link below.
• When participating in the HLPWs, participants can choose to be either an active participant or an observer.
• Active Participants:
  • Must join at least one TFG and actively participate (virtually) in its meetings during the time leading up to the final in-person workshop
  • Work performed on behalf of a TFG will be included in that TFG's summary presented by the TFG leader(s) at the final in-person workshop
  • Are encouraged to attend the final in-person workshop, but are not required to do so
• Observers:
  • Are welcome to join any TFG
  • Can still perform research on their own (or do nothing), but their work will not be shown or represented at the final in-person workshop
  • Can attend the final in-person workshop if desired
• Anyone is welcome to attend the final in-person workshop, subject to attendance limitations imposed by AIAA. The final in-person workshop is run by AIAA, and there is a fee associated with attending it. There is no fee to participate in the TFGs or any of the virtual meetings leading up to the final in-person workshop.

**Participation in HLPW implies agreement that any submitted results, grids, presentations, or other data will be made publicly available. Participants are responsible for obtaining necessary permissions from their own organizations prior to the workshop.
