Announcing the

5th AIAA CFD Drag Prediction Workshop

Sponsored by the Applied Aerodynamics TC

2-Day Workshop Preceding the 30th APA Conference

New Orleans, LA
23-24 June 2012

Objectives

• To build on the success of past AIAA Drag Prediction Workshops.
• To assess the state-of-the-art computational methods as practical aerodynamic tools for aircraft force and moment prediction of industry relevant geometries.
• To provide an impartial forum for evaluating the effectiveness of existing computer codes and modeling techniques using Navier-Stokes solvers.
• To identify areas needing additional research and development.
  

Focus

• The focus of this workshop will be to continue studies with the NASA Common Research Model (CRM) performed in DPW-IV.

General Information

• This workshop is open to participants worldwide. Efforts will be made to ensure representation from all areas of industry, academia and government laboratories.
• Participation in the drag studies is not required to attend the workshop. Everyone is welcome!
• Open forums will be included in the workshop to discuss the solutions and modeling techniques.
• Results will be made available after the workshop in a report and on the DPW website.
• A nominal registration fee will be required for attendance.
• AIAA membership is not required.

Test Cases

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.
