NACA0012 · AoA Sweep
A planned one-parameter branch focused on how changing angle of attack alters flow regimes, model assumptions and generalization behavior.
Use angle of attack to deliberately challenge the dynamics assumption
The AoA branch should not merely reproduce the speed-sweep workflow with a different x-axis. Changing α can alter separation, shedding structure, periodicity and the dimensionality of the flow, so dynamics classification becomes an explicit gate before model choice.
AoA anchor conditions
Choose low / mid / high α anchors first, then refine around regime transitions rather than immediately building a dense uniform sweep.
Periodic or not?
PSD, autocorrelation, repeatability and SPOD/DMD-style diagnostics where useful. Do not assume one phase coordinate remains valid.
Leave-one-AoA-out
Lock withheld α conditions before model selection. Separate interior interpolation from boundary extrapolation just as in the speed branch.
What this page will eventually contain
Second application of the same challenger track
Speed Sweep establishes whether PhysicsNeMo can improve the known POD/coefficient weaknesses on a controlled one-dimensional problem. AoA Sweep then tests whether the learned representation remains useful when the underlying dynamics themselves change.
