| 摘 要： | 采用反向蒙特卡罗法计算分析了加力式涡扇发动机非加力状态各固体壁面的有效辐射强度(包括自身辐射强度和反射辐射强度)、燃气辐射强度以及总辐射强度特性,并对它们的分布规律进行了讨论分析.结果表明:在新计算分析的状态中,中心锥是探测角度小于15°时的主要红外辐射源,在尾向贡献了最大辐射强度的65%以上;在探测角小于20°的范围...

| Abstract: | The effective infrared radiation intensity(self-radiation intensity and reflected radiation intensity),gas radiation intensity and total radiation intensity of afterburning turbofan engine under non-afterburning condition were calculated and analyzed using reverse Monte-Carlo method.The distributions of them were discussed and analyzed.The results show that,under the conditions given hereto,the cone is the strongest infrared radiation source,which contributes more than 65% to the maximum infrared radiation ... |
