Regime
Set by the Knudsen number — where the continuum stops
Every figure drawn under this hypothesis — 21 of them — with the essay each one belongs to and the generator that drew it.
21 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.
- Slip is a memory of one mean free path — air · which-memory-a-number-decides
- Slip is a memory of one mean free path — air at sea level · which-memory-a-number-decides
- Where a fluid stops being one — a long tube, diffuse reflection; the minimum is Knudsen's measurement and is drawn as one · rarefied-channel
- A gas's viscosity ignores its pressure until the free path reaches the walls — air at 300 K; Knudsen number from 10⁻⁷ to 10⁴ across three gaps · velocity-field
- Slip is a memory of one mean free path — Knudsen numbers from 10⁻⁶ to 70 — air at each case's own pressure and temperature, μ from Sutherland's law · rarefied-channel
- Where a fluid stops being one — dry air at 300 K, μ = 18.46·10⁻⁶ Pa s; the mean free path against pressure · rarefied-channel
