WALL-MODELED LES and LATTICE-BOLTZMANN TFG

4th AIAA CFD High Lift Prediction Workshop

and

3rd Geometry and Mesh Generation Workshop

The following gives the current membership of this Technology Focus Group (TFG). Names are given in alphabetical order, and Participant IDs (PIDs) are assigned for each name. (The PIDs may not be contiguous or in numerical order, as individuals may drop out and teams will use only one PID.) Please contact hiliftpw@gmail.com if you have a correction. If you are part of a team, please choose one member's PID that you will all use, and let us know.

Note that if you are a member of more than one TFG, you will have a different PID for each. When submitting results, you should include your PID as an identifier in all of your data submittal files. If you submit multiple sets of results to one TFG (for example, using different codes, different turbulence models, etc.), then append ".1", ".2", ".3", etc. in order to distinguish between them. E.g., if your PID is W-001, you would use W-001.1, W-001.2, W-001.3, etc. for multiple submission variants.

Each TFG has developed a list of Key Questions (KQs) that it will strive to answer for the purpose of the workshop. These are also listed below. TFG-specific documents (if any) are also provided here.

• Key Questions

  1. How sensitive are the integrated forces and moments (e.g. lift, drag, pitching moment coefficients) to the computational grid? (a) Will we be able to show convincing convergence with respect to the grid? (b) Can we define a credible process for verifying that the results are sufficiently converged, and what exactly would that process be?
  2. How do we handle the very thin boundary layer at the leading edge in a sufficiently accurate yet affordable manner?
  3. Will some kind of implicit time-stepping be necessary at realistic Reynolds and Mach numbers?
  4. What are the factors limiting accuracy and/or computational cost, and what is the estimated gain (in accuracy and/or cost) from improvements to each factor?
  5. Relevance of tripping used on the wing. Does tripping need to be explicitly represented, or numerical transition is sufficient?
  6. With the fuselage mounted on the tunnel wall, how important is it to characterize the tunnel boundary layer?
