二元塞式喷管红外特征及壁面降温的红外抑制效果计算

Numerical simulation of the infrared radiation characteristics and infrared restraining effect of lower wall temperature for two-dimensional plug nozzle

  • 摘要: 用数值计算的方法研究了涡扇发动机二元塞式喷管在3~5μm波段的红外辐射特性,并与轴对称收扩喷管进行了对比.结果表明:无冷却措施时,相比于轴对称收扩喷管,二元塞式喷管在大部分探测角度上红外辐射增强,只在小部分的探测角度范围内具有红外抑制作用,在窄边探测面内探测角为90°方向上,其红外辐射强度降低了54%.若塞锥后部壁面温度降低300K,二元塞式喷管在大部分探测角度范围内的红外辐射强度明显低于轴对称喷管,在正尾向上的红外辐射强度降低了57%;与轴对称喷管中心锥表面降低相同温度相比,二元塞式喷管能取得更高的红外抑制效果,并且所付出的冷却代价较小.
