摘要
用计算流体动力学(CFD)软件FLUENT,数值研究化学氧碘激光喷管形线,碘喷孔位置,副流入口压力,O2(1△)初始产额,水蒸汽含量以及稀释气体对平均小信号增益系数沿流动方向分布的影响;并对大连化学物理研究所超音速化学氧碘激光的两次实验进行数值模拟,计算结果显示平均小信号增益系数与实验测试的摩尔功率趋势一致.
Abstract
The computational simulations of the mixing flowfield of supersonic chemical oxygen-iodine laser (COIL) using FLUENT (CFD) computation of fluid dynamics commercial software have been performed. The distribution of the averaged small signal gain along the downstream for nozzle profiles, orifices locations, pressure of secondary flow, O2(1Δ) yields, content of water vapor and dilute gases was caculated. The numerical simulation for two experimental conditions of Dalian Institute of Chemical Physics show that the trend of the computational averaged small signal gain coincides with the measured output mole power.
