| 摘要: |
| 应用改进的移动火焰锋面(MFF)模型，分析了环境压力、温度等参数对碳颗粒燃烧过程的影响。在此基础上，研究了固冲发动机补燃室内碳颗粒的燃烧过程，得到了固冲补燃室环境中的碳颗粒燃烧特性，并通过固冲直连式试验验证了数值模拟结果。结果表明：补燃室中大部分碳颗粒在进气道出口附近燃烧。 |

| Abstract: |
| The effect of pressure and temperature on carbon particle combustion was studied by an improved Moving Flame Front (MFF) model. On the basis of the above discussion, the carbon particle combustion in solid rocket ramjet was analyzed. As a result, the carbon particle combustion mechanism in solid rocket ramjet was achieved. Moreover, numerical results were validated by direct-connect test of solid rocket ramjet. The result shows that most of carbon particle in the secondary combustion chamber burned near the inlet exit. |
