Overview and Summary of the Third AIAA High Lift Prediction Workshop

Abstract

The Third AIAA CFD High Lift Prediction Workshop was held in Denver, Colorado, in June 2017. The goals of the workshop continued in the tradition of the first and second high-lift workshops: to assess the numerical prediction capability of current-generation computational fluid dynamics (CFD) technology for swept, medium/high-aspect-ratio wings in landing/takeoff (high-lift) configurations. This workshop analyzed the flow over two different configurations, a “clean” high-lift version of the NASA Common Research Model, and the Japan Aerospace Exploration Agency Standard Model. The former was a CFD-only study because experimental data were not available before the workshop. The latter was a nacelle/pylon installation study that included comparison with experimental wind-tunnel data. The workshop also included a two-dimensional turbulence model verification exercise. Thirty-five participants submitted a total of 79 data sets of CFD results. A variety of grid systems (both structured and unstructured) as well as different flow simulation methodologies (including Reynolds-averaged Navier–Stokes and lattice Boltzmann) were used. This paper analyzes the combined results from all workshop participants. A statistical summary of the CFD results is also included.
