Regime
Ma below 0.3 — density effectively fixed
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.
- A big slow push — incompressible, Ma → 0 · free stream U = 1 · velocity-field
- A swept wall makes vorticity along its isobars, not across its flow — incompressible, Ma → 0 — an exact solution; the outer flow at 45° at this station · velocity-field
- Mass has nowhere to go — incompressible, Ma → 0 · free stream U = 1 · velocity-field · hero
- Mass has nowhere to go — incompressible, Ma → 0 · free stream U = 1 · velocity-field
