Experiment guide

Taylor–Couette flow is the motion of fluid between two rotating coaxial cylinders. The exact base profile obeys vθ(r) = Ar + B/r. Above a critical differential rotation, axisymmetric vortex cells may develop.

Use Laminar, Onset, Vortices and Counter for comparison. Orbit with drag, zoom with scroll. ⌁ injects a perturbation, ↻ resets the current run. CSV exports the sampled simulation history.

Limitations: this is a reduced-order educational model, not a Navier–Stokes solver. Ta≈1708 is a reference for narrow-gap flow with stationary outer wall; it is not an exact onset test when the outer wall moves.
