Regime
Linear stability of a parallel flow — an eigenvalue problem with no Reynolds number in it
Every figure drawn under this hypothesis — 6 of them — with the essay each one belongs to and the generator that drew it.
6 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.
- Every unstable wave is inside one circle — a tanh layer at k = 0.4, shifted by up to 3.5 · turbulent-exact
- Every unstable wave is inside one circle — a tanh layer, wavenumbers from 0.05 to 0.99 · turbulent-exact
- Sufficient, and not necessary — Ri from 0 to 0.2499 · turbulent-exact
- Sufficient, and not necessary — Ri from 0 to 0.2499 on a tanh layer · turbulent-exact
- Sufficient, and not necessary — Ri = 0.05 everywhere — a fifth of the threshold · turbulent-exact
- Sufficient, and not necessary — a stated velocity and density gradient, mixed to uniform over a layer · turbulent-exact
