Hi Jesse

My  interest peaked when I saw  'conformal

radiator'.  Where were you

planning on getting it made?  Good luck with your

Cozy IV.  That plane was

on my short list.  Still have a soft spot for it.

My wife thinks it's

'nice'. Perhaps next time.

Doug,

I was planning on making it myself out of either
aluminum or titanium.  I have friends who can weld
both pretty well.  Titanium is only about a dollar a
foot depending on the diameter and wall thickness.  I
have not checked on the heat transfer coefficient, but
I just like the stuff.

Yea I like working with the stuff as well. For corrosive saltwater
environments my company uses a lot. It is not so good for thermal
conductivity however.  Copper seems to be very good and aluminum a close
second.  Aluminum doesn't corrode as fast as copper hence I imagine the
change to aluminum radiator and of course it less dense. Titanium would be
good in the exhaust system I think.  Attached is a PDF file. Some charts on
the third page might be helpful.

Thanks for the pdf Doug but too big to publish.
We need to limit our jpg's and attachments to about 150 K or less.
Lots of us are still on dial up me included.
