| Abstract: | An efficient VertiCOIL with a square pipe-array jet-type singlet oxygen generator and without primary buffer gas was demonstrated in our laboratory. The most important motivation for no primary buffer gas is that it easily enables the use of a cryosorption pump as the vacuum pumping system, besides, it can greatly reduce the cost and volume of COIL systems for industrial applications. A nozzle bank, with a gain length of 11.7 cm, a subsonic iodine-oxygen mixing length of 4 mm and a designed Mach number of 2.5, is energized by a specially designed SPJSOG operating with no buffer gas. As a result of optimization of the SOG parameters, a maximum output power exceeding 2.25 kW with chemical efficiency of 21.1%, a nozzle exit flux of 64 W/cm2 and a specific power of 0.22 J/g were obtained for a |
