Regime
Second order in the amplitude — a mean flow driven by an oscillation with none
Every figure drawn under this hypothesis — 17 of them — with the essay each one belongs to and the generator that drew it.
17 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 drift made of two things that average to zero — second order in the amplitude ratio — a layer thin against the body, and Re_s small · mean-field
- A swimmer that cannot go backwards — creeping flow, Re → 0 — the expansion parameter kb runs to 0.4 here · moving-surface
- A swimmer that cannot go backwards — creeping flow, Re → 0 — the expansion parameter kb runs to 0.4 here · moving-surface
- A wave on the wall is a pump — Re → 0 and wavelength long against the channel — amplitude ratio 0.7 · velocity-field · hero

- An oscillation with somewhere to go — second order in the amplitude ratio — a layer thin against the body, and Re_s small · mean-field · hero
- An oscillation with somewhere to go — second order in the amplitude ratio — a layer thin against the body, and Re_s small · mean-field
- An oscillation with somewhere to go — second order in the amplitude ratio — the outer flow is inviscid and the layer supplies the condition · mean-field
- The better tunnel needs the bigger tank — incompressible tunnel water — 2 km of 3 m tunnel at 2 m/s, 5 m of friction · surge
- The drift in a wave that has none — second order in the amplitude ratio — a layer thin against the body, and Re_s small · mean-field
- The mean is not the flow — second order in the amplitude ratio — a layer thin against the body, and Re_s small · mean-field
