Organization / Localization: Univ. Lille/IRSN Facility Description: The system consists of a flat flame burner which allows to stabilize H2/O2/ Ar low pressure premixed flames seeded with known amounts of HI Test Identification: Tests IOH-1, IOH-2, IOH-3, IOH-4, IOH-5 SA-Related Topics / Phenomena:Reaction kinetics of gaseous iodine in oxidising atmospheres, particularly with an excess of steam Measured Parameters: Chemical species concentration (HI, H2O, OH), flame temperature Modelling: Flame conditions (gas composition,i.e. H2, HI, O2, Ar), carrier gas flow and composition, max temperature in reaction zone, residence time, iodine mass flow rate and mean concentration in high temperature zone Simulation Code: Chemkin
ASTEC/SOPHAEROS Experimental Research Program: Funded by the ISTP program and Electricité de France Link to PIRT: WP-1.5 ST-47
