The bottom bell curve opens up too fast as it progresses towards the
radiator.  You'll get flow separation and perhaps even a bubble (cylinder)
of turbulence that blanks from 1/3 to 1/2 of the radiator.

That is interesting Chris.  I was going to say that looked like the best

Kuchemann & Weber and even Hoerner for that matter. Look back in old messages.
We discussed this very extensively indeed. When did you come on board?
