Abstract

Abstract: Oblique detonation wave stabilized over a body has been studied due to the ongoing development of high-speed propulsion systems. In order to study the fine structure and its influence factor of oblique detonation wave, the phenomenon of wedge-induced oblique detonation wave was simulated numerically based on the reactive Euler equation using fifth-order WENO scheme. The numerical results show that with the compression of the wedge wall the detonation wave front structure is divided into three sections:ZND-like structure, single-headed triple point structure and dual-headed triple point structure. In addition the triple point traces are recorded to obtain different cell structures, in which the single-headed triple trace has the characteristics of parallel straight lines and the dual-headed triple trace is inclining cellular pattern. Influence of the inlet Mach number and wedge angle on wedge compressibility is also analyzed. Increase of the two parameters strengthens the wedge compressibility, which makes the detonation wave smooth. 

摘要： 为了揭示斜爆轰的精细结构及其影响因素,基于带化学反应的Euler方程,利用五阶WENO格式,对尖劈诱导的斜爆轰进行了数值模拟。结果表明,在劈面的压缩下,斜爆轰波阵面被分为三种结构,依次是类ZND结构、单三波点阵面结构和双三波点阵面结构。同时,根据三波点的轨迹绘制了胞格结构,其中单三波点的轨迹为平行直线,而双三波点的轨迹为倾斜的蜂窝状结构。讨论了来流马赫数和尖劈角度对劈面压缩性的影响,随着马赫数和劈角的增加,尖劈的压缩更厉害,爆轰波阵面也就越光滑。
