Six profiles with nothing in common but their two ends

The velocity profiles the theorem is tested on: a shear layer, the same layer rescaled, a jet, a wake, an asymmetric layer and a double shear layer. They differ in where they bend, how many inflection points they have and whether they are symmetric. The theorem uses none of that — only the largest and smallest speeds each one reaches.

5 essays call turbulent-exact. The drawing above is what it returns with no arguments at all; every call below passes it something, because a placement that passes nothing draws whichever member of the family the generator happens to default to rather than the one its essay argues about.

It is also the blast radius. Changing turbulent-exact changes every figure listed here at once, and on this site it may change what they assert as well as what they show — which is what has to be rebuilt and looked at before the change is believed.
