对燃烧室喷出的射入通道内的高温高速两相流进行了数值模拟．建立了考虑辐射及射流周围空气具有一定速度的气粒两相射流的数学模型和物理模型．利用积分方法求解了高温高速射流的速度分布和流量分布．利用网格离散的数值算法求解了温度分布．同时给出了颗粒相的浓度分布规律．计算结果在定性分析上是合理的．

The author make the numerical simulation for two-phase efflux with high temperature and velocity into the passage. Mathematical and physical model are established. In the model, radiation is considered and air around have a certain velocity. Distribution of velocity and flow are solved with analytical method, and temperature distribution is solved with numerical solution of grid dispersion. Meanwhile, distribution of concentration of solids is given. The result of computation is valid to qualitative analysis.
