The effect that was described was absolutely NOT a result of thermal conductivity being a function of temperature.
It was a dynamic effect... a transient condition. The result of applying a short heat pulse to a long Time Constant, distributed system. Do the simulation I suggested hours ago. -John ============== >> Tom >> >> The thermal conductivity isnt constant with temperature. >> It also varies between different crystalline forms of the same material. >> This can be seen in more comprehensive tables of thermal conductivity. >> In particular at cryogenic temperatures the thermal conductivity can >> change dramatically (eg in superconductors) >> >> Bruce > > Excellent.
