Overview of the First AIAA CFD High Lift Prediction Workshop (Invited)

An overview of the First AIAA CFD High Lift Prediction Workshop (HiLiftPW-1) is presented. The workshop focused on the capability of current generation Reynolds-Averaged Navier-Stokes (RANS) computational fluid dynamics (CFD) flow solvers to numerically predict the aerodynamic performance of swept, medium-to-high-aspect ratio wings in landing/take-off (high-lift) configurations. The workshop was held on June 26-27, 2010 prior to the 28 th AIAA Applied Aerodynamics Conference in Chicago, IL. The geometry configuration utilized was the National Aeronautics and Space Administration (NASA) Trapezoidal Wing (Trap Wing) high-lift wing/body geometry. The Trap Wing is a large chord, semi-span three-element configuration that was extensively tested in several NASA wind tunnels. A rich set of experimental data exists which was used in the comparisons with the CFD results. To promote consistency in CFD data comparisons and to ease the grid generation burden, several high quality, committee-generated grid systems were made available to participants. As part of the workshop, participants were encouraged to generate CFD results for a series of test cases using at least one committee-supplied grid system. If desired, participants could also create their own grid system using a specified set of grid generation guidelines. This paper describes the background and motivation for the workshop, details of the Trap Wing configuration and associated experimental data, summary of workshop test cases, and a description of the grid generation aspects of the workshop. A companion paper entitled “Summary of the First AIAA CFD High Lift Prediction Workshop” presents the CFD results, comparisons to the experimental data, and statistical analysis of the numerical results.
