| 摘 要： | 采用一维分离两相流反应模型以及变步长跳步差分计算格式,模拟了固体推进剂的燃烧转爆轰过程。计算结果详细、合理地描述了推进剂在燃烧转爆轰过程中的流场分布情况。文中建立了确定诱导爆轰距离(L_(DDT)的方法,由该法所得L_(DDT)的值与实验值符合得较好,其误差小于15％。

| Abstract: | In this paper, the simulation calculation of deflagration to detonation transition (DDT) process in solid propellant was carried out by use of one-dimensional separated two-phase reactive flow model and "Leap-Frog" method with variable time steps. The detailed condition of the flow field during DDT in propellant was described. A new method to determine the pre-detonation distance LDDT was presented. LDDT value obtained from the proposed method agrees with exprimental result within 15%. |
