Regime
Set by the Keulegan–Carpenter number — whether the flow has time to make a wake
Every figure drawn under this hypothesis — 20 of them — with the essay each one belongs to and the generator that drew it.
20 figure placements state this regime. The strip along the foot of every figure names two things — the model that produced it and the regime it holds in — and this listing is read back out of the finished drawing rather than from what produced it.
- A particle is a low-pass filter — Stokes drag, small particle Reynolds number · which-memory-a-number-decides · hero
- A particle is a low-pass filter — Stokes drag, small particle Reynolds number · which-memory-a-number-decides
- Long enough to make a wake — KC = U_mT/D — the excursion in diameters is KC/π · regime-collapse
- Long enough to make a wake — KC = U_mT/D, with β = D²/νT as the second number · regime-collapse
- Two forces, and only one of them remembers — a ten-second swell unless stated · which-memory-a-number-decides
- Long enough to make a wake — KC = U_mT/D from 1 to 200 — an oscillating flow past a fixed cylinder · regime-collapse
- Every memory number is one time over another — drag coefficient 1.2, inertia coefficient 2.0 — Morison's equation · which-memory-a-number-decides
