在实验基础上建立起描述多孔固体推进剂中燃烧转爆轰过程的一维反应两相流模型。用ＭａｏＣｏｒｃｍａｋ有限差分格式和自适应网格技术数值求解了控制方程。数值结果表明，在燃烧转爆轰的各个阶段，颗粒床都存在不同程度的动态压缩，压缩波和燃烧波的相互作用是燃烧向爆轰转变的内在原因。数值预测与实验结果进行了比较，两者有相当的一致性。
Based on the experiment, a one-dimensional two-phase reaction model describing the combustion-detonation process in porous solid propellant was established. The governing equations are solved numerically using MaoCorcmak finite difference scheme and adaptive grid technique. The numerical results show that the granular bed has different degrees of dynamic compression at various stages of combustion detonation. The interaction between the compression wave and the combustion wave is the intrinsic cause of the transition from combustion to detonation. Numerical prediction and experimental results were compared, the two have considerable consistency.
