Aerodynamicist Theodore von Kármán died and went to heaven.  In his
registration packet was a bright orange ticket.  Said Saint Peter,

"You may get in line to ask God Himself one question."

von Kármán ran to join the far end of the orange ticket queue.  It was
a long line, a *very* long line.  Eons passed by and, sure enough,
eventually in the distance he espied a giant glowing throne.  More
eons passed by and, finally, his moment arrived!

von Kármán surrendered his orange ticket, took a deep breath, and
said, "God, explain turbulence."

Theodore von Kármán spent the rest of eternity burning in Hell.

that is how bumble bees fly

they stack the the eddies(vorticies) to create compressed air which to
step the next wing flow on.

Because flows are more or less incompressible, all flow must go in a
loop. If you start with a container with zero flow, the next simplest
structure is a single vortex.
A general flow can be written as a superposition of vortices.

A topological examination was the idea of why do air current
structures exhibit only a vertical component relative to the flow
along the earth's surface.

A kind of special airflow occurs because the earth causes a relative
flow.  For example an infinite media has no relative direction.  A
special kind of flow would be a recirculation in a small area.
Infinite flow would be the only technical non-recirculation type of
air movment.  On earth larger recirculations such as high or low
pressure areas appear the common vortex.

SO in finite media, air must recirculate or compress.

An example of another type of circulation was the vertical vortex as
opposed to the compact vortex,  A wing of an airplane makes a special
tornado like vortex as opposed to the simple high or low pressure area
vortex.

So air must always behave as topology demands and non infinite media
without air compression must stir.  Stir as a cup of coffee.  The term
for topological solution was to identify the axis.  All media must
exhibit a solution to motion. A motion reference point is caused by
the first momenta transfer to the media.  IN diagram

o-

o means a motion whereas the "-" means the from a point act.  Making
the place flow moves from a true coordinate.  ALL finite media exhibit
flow with coordinate.

A river bank in 2D analogy to air flow models ducted air flow.  A duct
side would alter topological coordinate to cause another non-vortex
kind of motion.  A reversal of direction as the recirculation type
appears far different from single point coordinate recirculation.

A line or duct wall causes a flow gradients in ducts.  Making upstream
and down stream turns of motion allowable.

There is no upstream to a high or low pressure system.  What is
interesting is how to alter toplogy to cause a special air flow to
allow novel wind turbines.

Here is a simple alteration. Place a stick on the earth and cause air
to flow along the length of the stick.  Or point the stick along the
wind vector.  Make a long vortex only wind turbine, deny air the
ability to locally recirculate.  A wall of a duct enforces zero
recircualtion for its length. How can this be done in a ductless
fashion? It can.
