| 摘 要： | 运用离散颗粒模型对固体火箭发动机及尾焰两相流进行了一体化仿真,得出了各燃气组分和Al2O3颗粒的流场参数分布.通过建立固体火箭尾焰红外辐射模型,计算出了二维轴对称尾焰的光谱辐射亮度.研究表明,颗粒辐射起着主导性作用,颗粒尺寸越小,在4.3 μm波长处气相辐射作用越明显;燃烧室内燃面颗粒速度越大,尾焰辐射越弱;颗粒尺寸越大,颗粒辐射越强,但随燃面颗粒速度增大,辐射降低越快.所得结论与相关文献数据一致,表明计算模型和方法可行. |

| Abstract: | The two-phase flow of solid rocket motor and exhaust plume was numerically simulated by using discrete particle model.Flow field parameters distribution of gaseous ingredients and Al_2O_3 particles were acquired.Spectral radiance of two dimension axial symmetry plume was computed through the development of infrared radiation model of solid rocket exhaust plume,and comparison with that in document.The study shows that the radiation of particles plays dominant role in the infrared radiation of exhaust plume,a... |
