Abstract

Experiments with a small scale jet-type singlet oxygen generator (SOG) for a chemical oxygen iodine laser (COIL) were performed in order to find a suitable parameter for scaling to generators with higher chlorine flow rates. The results of various parameter variations (e.g. overall gas-flow rate, type of diluent gas, length of reactive zone) are shown. Additionally, different types of BHP-injection systems were tested trying to find the best performance of the SOG. The first jet plate is made of Lucite with 49 holes of 0.8mm diameter. Two rows of holes in front of the generator exit are fitted with small injection needles to prevent liquid spill-over. A similar jet plate was designed but with all 49 holes fitted with needles. In another experiment, the diameter of the BHP-jets was varied maintaining a constant total cross-sectional area. A new “sprinkler-type” BHP-injection system is presented, too. On the basis of the previous results a 10kW jet generator was designed and adapted to the 10kW DLR generator test stand. The generator was optimized regarding liquid spill-over. Stable generator operation without liquid spill-over could be demonstrated. The utilization reached values over 90%.
