HIGH-LIFT PREDICTION WORKSHOPS: RETROSPECTIVE, LESSONS LEARNED, AND FUTURE PROSPECTS
C.L. Rumsey, NASA Langley Research Center, United States
The AIAA High-Lift Prediction Workshop (HLPW) series has been ongoing since 2010. At these workshops, engineers interested in computationally predicting the flows over high-lift configurations have compared and collab-orated with others in an effort to further the goals of the workshop. These goals include: (1) assessing 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) developing practical modeling guidelines for CFD prediction of high-lift flow fields; (3) deter-mining 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) enhancing CFD prediction capability for practical high-lift aerodynamic design and optimization.rnBy the time of the 34th ICAS Congress, five HLPWs will have been completed, and still more workshops are planned for the future. Significant progress has been made in the workshop process itself, encouraging a more rapid rate of learning and faster dissemination of knowledge and ideas to the high-lift prediction community. This paper will provide a 14-year retrospective on the workshop series, including its trajectory over the years, what has been learned, what still needs to be accomplished, and how integrated validation testing plays a critical role.
