The 5th AIAA CFD High Lift Prediction Workshop (HLPW-5) Sponsored by the AIAA Applied Aerodynamics Technical Committee Page under construction This site is under development for HLPW-5. HLPW-4 was held in January 2022; you can find details at: https://hiliftpw.larc.nasa.gov/index-workshop4.html. 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)). Please sign up (see the AIAA HLPW Committee's CONTACT info below) to be kept informed about the workshop. If you are already on the HLPW mailing list from previous years, then you don't need to do anything. 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 will be conducted in a similar way to HLPW-4, with virtual collaboration during the months leading up to the workshop. These collaborative efforts will be accomplished through "Technology Focus Groups" (TFGs). The TFGs will cover specific areas of interest, such as Fixed Grid RANS, Mesh Adaptation, High Order Discretization, Wall-Modeled LES, and Hybrid RANS/LES. The teams have yet to be formed... more details about the TFGs to come later. 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.
