为评估化学激光器燃烧室中爆轰的影响,分析了氟化氘(DF)化学激光器在某次出光实验中燃烧室产生的爆轰问题,采用时空守恒元与求解元(CE/SE)方法对该爆轰过程进行了数值模拟。结果表明,燃烧室中爆轰的产生与传播使得燃烧室瞬态压力剧增,由此产生的振动、冲击和扭矩作用导致光学谐振腔失调,从而影响了激光器的正常出光。研究结果对DF激光器的优化设计及安全运行具有指导作用。 In order to evaluate the impact of detonation in the chemical laser combustor, the detonation problem in the combustion chamber of a deuterium fluoride (DF) chemical laser was analyzed. The time-space conservation element and the solution element (CE / SE) The detonation process was numerically simulated. The results show that the generation and propagation of detonation in the combustion chamber make the instantaneous pressure surge in the combustion chamber. The vibration, shock and torque generated in the combustion chamber lead to the optical resonator imbalance, which affects the normal light output of the laser. The results of this study can guide the optimal design and safe operation of DF lasers.
