High Lift Prediction Workshop

The AIAA CFD High-Lift Prediction Workshop is a collaborative effort organized by the American Institute of Aeronautics and Astronautics (AIAA) to advance the state-of-the-art in computational fluid dynamics (CFD) for high-lift aircraft configurations. These workshops focus on verification and validation of CFD methods for complex high-lift systems, such as transport aircraft with deployed flaps and slats during takeoff and landing conditions. Participants use standardized test cases, geometries, and committee-generated computational grids to assess the accuracy of various turbulence models, numerical schemes, and computational approaches in predicting the challenging flow physics associated with high-lift configurations. The workshops serve as important benchmarks for the CFD community, identifing strengths and limitations of current methods and helping to guide future research directions in high-lift aerodynamics prediction.

Goals of the Workshop

  • 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.

news

Sep 02, 2026 Date and time for Mini-Workshop 2 finalized and posted above. We’re also working towards having an experimental version of test-case 1 available by the end of September. This will feature a few minor changes relative to TC1, such as bracket shape and flap support structure, but more importantly will include a viscous test section to replicate what will be tested at University of Washington in the Fall.
Apr 30, 2026 Submission github page for Test Case 1 has been publicly launched! Further instructions for submission/ creating your own branch are included here
Mar 25, 2026 Updated TC1 Post Processing information, including two new views, and a single Tecplot layout that captures all requirements.
Mar 16, 2026 Added HRLES Grid Family H.1.TC1.01.
Mar 09, 2026 Added post processing information for HLPW6 Test Case 1.
