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 ...
