The vortex sheet on a flat plate, and where it goes to infinity

The strength of the vortex sheet that represents a flat plate at six degrees of incidence, along the chord. It falls to zero at the trailing edge, which is the Kutta condition, and it grows without bound at the leading edge as the inverse square root of the distance. The dashed line is that square-root law. The area under the whole curve is the circulation and is finite; the surface velocity it implies is not.

2 essays call edge-suction. 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 edge-suction 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.
