* After having looked at Mr. Evil's latest test page *

Very nice method to do the test simply

I would suggest you do a run with flat plate as a control.

Other suggestions offered for your current test method (since you aren't using a processor for the heat source) -

1) use PVC pipe instead of copper to eliminate any possible influence of the connection between the plate and the pipe (variance in the thermal properties of the weld) as well as any flow characteristic variances do to the pipe itself (dents, inner surface roughness, etc.)

2) use a non-stick pliable thermal pad for the interface between the test metal and "heat plate/source" to help eliminate the possible effects of variance in the thermal interface between the two, both due to mating surface features (flatness, smoothness, etc.) and possible variances in the thickness or coverage of the thermal epoxy.
