Test Cases

Five series of computations are included:
  1. Verification Study: 2D NACA0012 Airfoil from the Turbulence Modeling Resource (TMR) sponsored by the AIAA Fluid Dynamics Technical Committee Turbulence Model Benchmarking Working Group (TMBWG). Flow conditions are: M = 0.015; Re = 6 million; angle-of-attack = 10 degrees; Farfield boundary condition at 2,400 chords. Solution converged on either adapted or fixed sequence grid family. For more information on the TMBWG, see their website at: turbmodels.larc.nasa.gov.
  2. CRM Nacelle-Pylon Drag Increment: Calculate the drag increment between the CRM wing-body-nacelle-pylon (WBNP) and the CRM wing-body (WB) configurations. Flow conditions are: M = 0.85; Re = 5 million; fixed CL = 0.5 +/- 0.0001; aeroelastic deflections at the angle-of-attack 2.75 degrees geometry. Grid convergence study on Baseline WB and WBNP grids.
  3. CRM WB Static Aero-Elastic Effect: Angle-of-attack sweeps will be conducted using the aero-elastic deflections measured in the ETW Wind Tunnel Test. Flow conditions are: M = 0.85; Re = 5 million. Angle-of-attack sweep = [2.50, 2.75, 3.00, 3.25, 3.50, 3.75, 4.00] degrees. Use the Medium Baseline grids [7 solutions on 7 grids].
  4. CRM WB Grid Adaptation [Optional]: Fixed lift condition for the CRM Wing-Body using an adapted grid family provided by the participant. Flow conditions are: M = 0.85; Re = 5 million; fixed CL = 0.5 +/- 0.0001; aeroelastic deflections at the angle-of-attack 2.75 degrees geometry. Start the adaptation process from the Tiny (or Coarse) Baseline Mesh. Participants are to document the adaptation process.
  5. CRM WB Coupled Aero-Structural Simulation [Optional]: Fixed lift condition for the CRM Wing-Body coupled with computational structural analysis. Flow conditions are: M = 0.85; Re = 5 million; fixed CL = 0.5 +/- 0.0001; aeroelastic deflections at the angle-of-attack 2.75 degrees geometry. Use the Medium Baseline Grid. A structural FEM will be supplied by NASA via the CRM Website. Modal shapes will also be made available.

Geometries

Geometry files will be released at this location.

Grids

Standard grids will be available for all required configurations.

Any additional grids used to create submitted results must be provided to the DPW Committee.
