For a second time, the high-lift prediction and geometry and mesh generation groups are combining efforts in an all-inclusive joint workshop that seeks to understand and improve our ability to model, mesh, and simulate high-lift flows in an accurate and consistent manner. The common model used as the basis of this joint effort is the High-Lift Common Research Model (CRM-HL).

Overall, the goals of the GMGW series are to assess the current state-of-the art in geometry and mesh generation technology and software as applied to aircraft and spacecraft systems. The series seeks to identify and develop an understanding of areas of needed improvement (performance, accuracy, applicability) in geometry and mesh generation technology software, as well as to provide a foundation for documenting best practices for geometry and mesh generation.

The goals of the HLPW series are to: (1) 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; (2) Develop practical modeling guidelines for CFD prediction of high-lift flow fields; (3) Determine the elements of high-lift flow physics that are critical for modeling to enable the development of more accurate prediction methods and tools; and (4) Enhance CFD prediction capability for practical high-lift aerodynamic design and optimization.

Additional Information:

This combined workshop will be conducted differently than previous HLPWs or GMGWs. Technology Focus Groups (TFGs), composed of members and participants from both workshops, have been working closely together over the last year with the intent of answering key questions central to the CFD community's ability to mesh and compute on complex high-lift aerodynamic configurations.  Data generated and collected from these TFGs will be presented at the workshop.

Workshop participants and attendees will hear summary presentations covering the following general topics: (1) Geometry Modeling and Preparation for Meshing; (2) Fixed Grid RANS; (3) Mesh Adaptation for RANS; (4) High Order Discretization; (5) Hybrid RANS/LES; and (6) Wall-Modeled LES and Lattice-Boltzmann. There will also be general discussions regarding summary lessons learned and next steps forward.

The combined HLPW-4/GMGW-3 event will be hybrid. Participant registration is available both for in-person attendance as well as online (virtually via zoom).
