Abstract

Oblique detonation waves (ODWs) have been widely studied due to their application in hypersonic propulsion. Most of the previous studies focus on hydrogen fuel, and the induced wedge is always infinite. In this paper, based on the detailed chemical reaction model, the two-dimensional multi-component Euler equations are solved, and the finite wedge-induced oblique detonations for acetylene-air mixtures are investigated numerically and theoretically. Effects of expansion waves, inflow Mach number and equivalence ratio (ER) on initiation characteristics of ODW are studied according to the initiation criterion in the confined space. Results show that the initiation distance of acetylene is relatively larger than the hydrogen fuel, and the convergence position of deflagration waves and the originated position of expansion waves determine the initiation characteristics of ODW. As the originated position of the expansion wave is downstream of the convergence position of the deflagration, the ODW is ignited; Otherwise, the ODW is not initiated. The characteristics length of induction zone presents a U-shaped curve distribution for different ERs, both fuel-rich and lean-burn conditions will result in the non-initiation of ODW.

摘要

斜爆轰波在高超声速推进具有重要的应用潜力, 受到了研究者们的广泛研究. 以往的研究, 大多基于氢气燃料, 且楔面总是 无限长的. 本文基于详细的化学反应模型, 通过求解二维考虑基元反应的多组分欧拉方程, 对乙炔-空气混合物在有限长楔形面诱导 的斜爆轰进行了数值和理论研究. 根据受限空间内的起爆判据, 研究了膨胀波、来流马赫数和当量比对斜爆轰波起爆特性的影响. 结果表明, 乙炔诱导的斜爆轰波的起爆距离相对大于氢燃料诱导的. 爆燃波的会聚位置和膨胀波的产生位置决定了斜爆轰波的起 爆特性. 当膨胀波的产生位置在爆燃波会聚位置的下游, 斜爆轰波被点燃; 否则, 斜爆轰波不会起爆. 诱导区特征长度在不同当量 比下呈U型曲线分布, 无论是富燃还是贫燃都会导致斜爆轰波不起爆.
