NASA 2DZP — 2D Zero-Pressure-Gradient Flat Plate

Validation case from the NASA TMR Collaborative Testing Challenge 2022 (turb-prs2022).

Required metrics

1. Cf vs. x — skin-friction along plate
2. u⁺ vs. log₁₀(y⁺) at x = 0.97 — boundary-layer profile compared with theory

The full OpenFOAM case (mesh, fields, run scripts, extraction code) is hosted separately on the heavy CFD-asset Hugging Face dataset linked in the paper.

Solver / setup

• Solver: rhoSimpleFoam (compressible steady)
• Turbulence model: kOmegaSST (baseline, no augmentation)
• Grid: 545 × 385, finest of NASA TMR sequence
• Re_L: 5×10⁶ (L = 2)
• Inflow: M = 0.2

Submission format

Provide two files (CSV or Tecplot .dat) matching the columns of the bundled baseline:

• 2DZP_cf.csv — columns: zone, x, Cf
• 2DZP_u+y+.csv — columns: zone, log(y+), u+

Then python plots/plot_profiles.py overlays the baseline + reference + your model.
