Re: REFLECTOR:NACA inlet shapeI have seen it expressed though that according
to that original research that NACA scoops are not really suited for
application of heat exchange cooling. I need it to cool a radiator in my
application. Those that know more than I seem adamant that they do not work
well (even making reference to an alleged Velocity builder/flyer who hates
them). However, it seems as if Velocity, Inc. overall has had good results.
Any of you engineering (or programmers, or burger flippers etc) types have
any thoughts on this.
Thanks for your insight and experience.
All the best,
Chris

For the real enthusiast you can download the original NACA research paper
written in 1945. I'm not at home and don't have the reference but if you go
to www.larc.nasa.gov and then search their archive you should be able to
find it OK. The file is called naca-acr-5120.pdf it's about 12MB, title is
"An experimental investigation of NACA submerged-duct entrances".
In there you'll find recommendations for the shape of the duct and also
the shape of the lip on the wide end of the duct.
Fascinating stuff..
