I'd be interested in hearing opinions on this govt. report,

"Properties of Special Types of

Radiators" .  I interpret it as stating that auto rads make lousy

airplane rads and that a flat

plate rad , 12-20" deep with 1/2" spacing is far superior.  the math

is over my head, but that

charts are neat and simple.    kevin

I think the key here is that this is for radiators placed in the free
stream; i.e., no entrance ducting to slow down and expand the air flow
for pressure recovery.
