Gordon,
On the FIA cylinder heads, the water passage is external to the
cylinder head. Long tube, with runners going directly into the
head.
There is a lot of engineering on fluid dynamics, and cooling of
cylinder heads, etc. It would make for an interesting University
Project to determine the model for the cooling, and dynamics
involved.
There is some black conductive paper (forget the name of it), that
you could cut, punch holes in, etc. Apply an electric current across
it (which is heat in our case), and measure voltages across the paper
to determine "hot spots". I was working with packaged electronics,
that used a small external radiator for cooling. Oddly enough, my
"black paper" did a good job of explaining the hot spots in the package.
Hmm, wonder if I could use conductive foam to model a cylinder head
and the hot spots.
Cheers,
Tom
