JSOG中水蒸汽含量的模拟计算
Simulation of water vapor content in JSOG for COIL

摘要: 氧碘化学激光（简称 COIL）系统中，水是影响激光功率输出的最重要的原因之一。气流中的水不仅对激发态碘原子有严重的猝灭作用，另外对碘分子解离、超音速流动特性也有很坏的负面作用。单重态氧发生器的BHP（Basic Hydrogen Peroxide ）溶液是最主要的水蒸汽源。利用传质模型对射流式单重态氧发生器（简称JSOG）中产生的水蒸汽进行了计算，所得的数值结果与实验测量结果基本相符。根据模拟结果，对发生器的设计及实验条件进行了优化。Abstract: In Chemical Oxygen-Iodine Laser (COIL) system, the water vapor produced from the generator of singlet oxygen can have severe negative effects on the output of the laser power. In this paper, the water vapor content in the counter-flow Jet type Singlet Oxygen Generator (JSOG) is simulated. The results agree well with those of experiments. By way of simulation, some of the experimental conditions for JSOG are optimized to reduce the water vapor content.
