摘 要: 通过数值模拟,描述驻定斜爆轰(oblique detonation wave, ODW)和旋转爆轰(rotating detonation wave, RDW)的流场和胞格,并对各自的结构特征和自持机理进行分析。斜爆轰阵面由3个部分组成,依次是类ZND阵面,单三波点阵面和双三波点阵面。旋转爆轰阵面的胞格结构不均匀,外侧胞格小于内侧胞格。
关 键 词: 爆炸力学;推进系统;胞格结构;自持机理;经典CJ理论

Abstract: In this paper, the calculated cellular structures and flow fields of oblique detonation wave (ODW) and rotating detonation wave (RDW) are obtained numerically, and the fundamental characteristics and self�sustaining mechanisms of those detonations are analyzed and discussed. ODW front consists of three parts: the ZND�like front, the single�headed triple point front and the dual�headed triple point front. Cellular structures of RDW front are heterogeneous, and the cell size along the outer wall is smaller than that along the inner wall.
Key words: explosion mechanics; propulsion system; fundamental characteristics; self�sustaining mechanisms; classic CJ theory
