| 摘 要： | 为了评估反舰导弹喷管和尾流在超音速飞行状态下的流场特性和红外辐射特性,以"雄风3"反舰弹的尾喷管为研究对象,建立了相应的二维仿真计算模型.流场计算结果表明,凝相颗粒对尾喷流的流场特性有显著影响.相比于纯气相,加入凝相颗粒后喷流轴向高温区长度明显增加,马赫数下降更快.红外辐射特征计算结果表明,喷管及尾流的红外辐射特征表现...

| Abstract: | In order to evaluate the flow field characteristics and infrared radiation characteristics of the anti-ship missile nozzle in supersonic flight state,the nozzle of“Xiongfeng-3”anti-ship missile is taken as the research object and the corresponding two-dimensional simulation model is established in this paper.The calculation results of the flow field show that the condensed phase particles have a significant effect on the flow field characteristics of the jet.Compared with the pure gas phase,the length of the axial high-temperature zone increases obviously with the addition of condensed particles,and the Mach number decreases faster.The calculation results of infrared radiation characteristics show that the infrared radiation characteristics of the nozzle and wake show strong symmetry.The maximum radiation intensity appears when the yaw angle is 60°,and the radiation intensity reaches 103.68 W/sr. |
