VICON程序模拟氧碘化学激光器3维喷管流场的可行性探讨
Feasibility of numerical simulation of flow through COIL 3-D nozzle with VICON code

摘要: 用VICON程序对化学氧碘激光器(COIL)喷管冷流场进行了3维模拟，得出的计算区几何较准确地反映了模拟装置的几何变化。主气流方向和副气流方向的分点数反映出了此2维平面内的气动特性，对不同流量的模拟结果对比分析得出穿透过度与穿透不够一样，致使主副气流混合不好。对带化学反应的情况进行了模拟，显现出副气流从喷孔出来后穿进主气流的马蹄形结构的变化过程，这些说明VICON程序可用来模拟研究COIL喷管流场特性。Abstract: VICON code was used to simulate COIL cold flowfields, and the obtained geometry nicely reflected the geometry change of the simulated equipment. The grid dimensions of primary and secondary flow reflected gas characteristics of the two dimension plane. The simulation results of different flux showed that excess or insufficient penetration led bad mixing. Changing process of horseshoe that secondary flow came out from orifice and entered primary flow was showed by simulation of chemical reaction. Those show that the VICON code may be used to study flowfield properties on COIL nozzle.
