Anybody please check this calculation :-) About the graphs you posted, I see your point, at some low pressures the T_glassout decreases (especially with Helium). But the general trend is that at high pressures (>3 bar) the temperature drops. This is consistent with Gipsel interpretation: compressed gas cools the wire by convection and hinders IR radiation. Then the thermocouple reads a lower value because it sensitive to IR radiation. By the way, the pressure dependence is not related to emissivity at all, it's just cooling by convection.]]> 123star Wed, 19 Dec 2012 01:23:15 +0000 http://www.quantumheat.org#comment-1450
