Test Cases

Three series of computations are included:
  1. Common Grid Study: A multi-block, O-O grid topology has been generated for the wing-body configuration. Each cell edge has been divided in two up to eight times successively to develop a grid-refinement sequence. The resulting cloud of points will be reformatted into overset and tet-based unstructured grids. Within this series of eight grids, there will be a suitable grid refinement sequence for most types of grids. Additional computations are encouraged with user-developed grids (optional).

  2. Buffet Study: Alpha sweeps will be conducted at finely-spaced intervals through the zone where wing separation is expected to begin. Details of the exact CL-alpha combination for separation onset and patterns are to be reported.
  3. Turbulence Model Verification (Optional): In conjunction with the Turbulence Model Benchmarking Working Group (TMBWG), associated with the AIAA Fluid Dynamics Technical Committee, we are including three cases to study implementation of turbulence models in a controlled study. For more information on the TMBWG, see their website at: turbmodels.larc.nasa.gov.

Geometries

Geometry files were revised on November 7, 2008. Please ensure that you are using the revised geometry.
