Data Summary from Second AIAA Computational Fluid Dynamics Drag Prediction Workshop

Abstract

Results from the Second AIAA Drag PredictionWorkshop are summarized. The workshop focused on absolute
\nand configuration delta drag prediction of the DLR, German Aerospace Research Center F6 geometry, which is
\nrepresentative of transport aircraft designed for transonic flight. Both wing–body and wing–body–nacelle–pylon
\nconfigurations are considered. Comparisons are made using industry relevant test cases that include single-point
\nconditions, drag polars, and drag-rise curves. Drag, lift, and pitching moment predictions from several different
\nReynolds averagedNavier–Stokes computational fluid dynamics codes are presented and compared to experimental
\ndata. Solutions on multiblock structured, unstructured, and overset structured grids using a variety of turbulence
\nmodels are considered. Results of a grid-refinement study and a comparison of tripped transition vs fully turbulent
\nboundary-layer computations are reported.
