| 摘 要： | 足够强的激波扫过铺有可燃粉尘的界面时，波后形成燃烧的粉尘云边界层。为揭示其内部结构，本文对该现象进行了实验和理论两个方面的研究。理论计算表明燃烧粉云边界层可分为三个区域：诱导区、反应区和扩散区，诱导区的粉尘浓度最高，计算获得的粉尘云轮廓和点火延迟与实验结果基本吻合．

| Abstract: | When a sufficiently strong shock wave passes over a surface laden with com-bustible particle,a combustion dust cloud will be induced within the boundary layer,whichis investigated both experimentally and theoret ically to reveal its structure,It is shownfrom the computational results that the combustion dust cloud boundary layer consists ofan induction zone, a reaction zone and a diffusion zone。 The highest particle concentrationoccurs in the induction zone。 Computed and measured results for the profile of ... |
