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 Per-oxide )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。
Oxygen iodide chemical laser (COIL) system, water is one of the most important reasons that affect the laser power output. The water in the gas stream not only has a severe quenching effect on excited iodine atoms, but also has a very bad negative effect on the dissociation of iodine molecules and the supersonic flow characteristics. The singlet oxygen generator BHP (Basic Hydrogen Per-oxide) solution is the most important water vapor source. The mass transfer model is used to calculate the water vapor generated in the jet singlet oxygen generator (JSOG). The numerical results obtained are in good agreement with the experimental results. According to the simulation results, the generator design and experimental conditions were optimized.
