| 摘 要： | 建立了描述固体推进剂裂纹腔内瞬时对流燃烧过程的数学模型，数值求解该数学模型得到了气相参数沿裂纹长度方向的分布，通过对比定量地讨论了裂纹变形对裂纹腔内对流燃烧流场的影响，其结果为裂纹不变形假设的合理使用提供了理论依据。

| Abstract: | A theortical model describing the transient convective combustion inside a solid propellant crack cavity is developed.The distribution of gas parameters is obtained by solving the model numerically.The effect of crack deformation on convective combustion flow field in the crack is studied by comparing the calculated parameters with deformation to that without deformation.The obtained conclusions provide a theoretical basis for the applying of the assumption of propellant crack without deformation. |
