The temperature a film makes for itself

Plane Couette flow of oil between walls held at the same temperature: the velocity on the left, the temperature on the right. The velocity is a straight line and the temperature is a parabola, because the heating is uniform and the conduction is not. The peak rise is μU²/8k — 17.9 kelvin for these numbers — and it contains no gap and no length at all: a thinner film shears harder in exactly the proportion that it has less fluid to heat.

1 essay calls shear-heat. 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 shear-heat 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.
