| 摘要: |
| 本文在固体火箭发动机燃烧室中两相流动基本方程的基础上，导出了同时考虑侵蚀燃烧和两相流动的计算方程组，详细讨论了方程的数值求解方法，分析了侵蚀燃烧引起的通道横截面积沿长度的变化和两相流动对压力—时间曲线及燃烧室流场的影响，有利于准确预估压力—时间曲线和理论计算燃烧室中的流场。 |

| Abstract: |
| Based on fandamental equations for two-phase f1ow in combustion chambers of solid propellant rocket motors，this paper derives calculation equations taking into accoant erosive burning and two-phase f1ow. A numerical solution to these equations is discussed in detail; the effect
of variabi1ity of cross-sectional area of channel along the 1ength， which is caused by erosive burning，and two-phase f1ow on pressure-time curves and f1ow field in chambers is analysed. It is useful for predicting pressure-time curves accurately and calculating f1ow field in chambers thoretically. |
