An interior view of the FBCE-CM-HT test section. Test fluid is vaporized and pumped through the steel tube embedded in an insulating material while space station cooling water is flown around the outer annulus of the steel tube causing the internal vapor to condense. Both cooling water and test fluid temperatures are measured using a system of
thermocouples to calculate heat transfer. Image courtesy of NASA Glenn Research Center.
