Paper Abstract

Five major methods of preparing active medium in supersonic COIL are analyzed: (1) `classical' case with upstream SOG primary buffer gas and chlorine premixing, injection and dissociation iodine vapor in the subsonic region of the supersonic nozzle; (2) mixing oxygen stream with primary buffer gas (may be cooled) downstream of SOG; (3) iodine vapor injection into boundary layers of the trans-sonic region of the small-scale grid nozzle; (4) mixing of the coflowing supersonic jets of pure oxygen and N2 + I2 mixture at close static pressures and Mach numbers; (5) mixing of co-flowing sonic (or supersonic with small Mach number) pure oxygen jets and high velocity head supersonic N2 + I2 jets for reaching very high active medium recovery pressure.
