Paul,
        Looking at a wedge duct calling the opening or inlet the front and the far
closed end the back, and the bottom or tapered curved section the
floor.  What shape should the sides be?  I believe the version You tested
had flat sides.  Would it make any sense to use a bell shaped curve (K&W)
on the side walls to promote flow through the out perimeter of the
radiator?  Maybe it is not necessary but I just wanted to optimizes the
duct.  Thanks for any help.

When you get into 3D I don't really know. You are now on your own.
Optimizing something like that might take a lot of iterations while
surveying the velocity of the out flow all over the back side of the rad.
My guess it would be a combination of Kays & London and Kuchemann & Weber's
bell shaped duct. To my knowledge nothing like this has been
done so far.

Also that assumes the back side is totally unobstructed and free
to the atmosphere. Kays & London work was done in 2D as was my
full scale rad core test.

That means the sides of the wedge were 90 degrees to the surface
of the core. If you do some R&D on this I would love to
see the results.
