A mathematical study of the formation of a
boundary layer at the leeward side
of an obstacle, such as a wire or a leg of an oil rigg.
This one showed that earlier work had ignored small, but very important
effects, and had derived incorrect results.
That work had concluded that the flow cannot fully
be solved and tried
to guess the missing part. The guess was close, but not close enough.
