APPROXIMATE ANALYTIC SOLUTION FOR THE DISSOCIATION OF MOLECULAR-IODINE IN THE PRESENCE OF SINGLET OXYGEN

A computational study including sensitivity, nondimensional, and stead y-state analyses of the gas-phase kinetics associated with Chemical Ox ygen-Iodine Lasers (COIL) was performed to develop a simplified kineti c model and assess kinetic limitations to laser performance. A minimal set of 13 reactions is developed that adequately describes the time e volution of the major chemical constituents of a COIL device. A charac teristic time for the dissociation of molecular iodine by singlet oxyg en is established in terms of iodine fraction, water content, yield of singlet oxygen, and rate parameters. Finally, an approximate analytic solution to the iodine dissociation problem is established for a broa d range of reagent concentrations. The current study is Limited in app licability due to the exclusion of chemical heat release and reactive mixing phenomenon. (C) 1995 John Wiley and Sons, Inc.
