Regime
Re_p below 10 in a bed — Darcy's law, and the linear term carries it
Every figure drawn under this hypothesis — 3 of them — with the essay each one belongs to and the generator that drew it.
3 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.
- The bed that weighs itself — Re_p 0.1 at the corner — 100% of it viscous · bed-flow
- The bed that weighs itself — Re_p 0.1 at the marked point — between the two limits · bed-flow
- A permeability that is only the geometry — the same bundles at porosity 0.3 — Darcy's law, Re_p = 0.01 · applied-total
