-
摘要: 实现了对射流式氧发生器的三维仿真模拟，给出了氧发生器内部流场结构、各组分的分布状态等信息。研究了射流孔结构对氧发生器性能的影响。指出即便是具有相同比表面积的不同射流孔排布方式，也会对发生器性能产生影响。此外，逆向射流式氧发生器反应器中气体从双侧进入对于减小发生器对气体的阻力具有重要作用。Abstract: Jet singlet oxygen generator is the most stable energy generating device for the chemical oxygen iodine laser.The three dimensional simulation of the jet chemical oxygen iodine laser is presented,which shows the structure of flow field in the re-actor and the distribution of the components.It is pointed out that arrangement of liquid jets influences the operation of jet singlet oxygen generator under the same specific surface area.Moreover,the jet singlet oxygen generator with two gas entrances has a lower flow channel resistance compared to that with single gas entrance under the condition of the same flow.These results are meaningful for further optimization of jet singlet oxygen generator.
