摘要/Abstract

摘要： 采用9组分19步的基元反应模型,忽略黏性、热传导和扩散等输运效应,对以2H₂₊O₂₊₄N₂为反应混合物的旋转爆震发动机进行了二维模拟。采用分段填充方法起爆旋转爆震波,研究结果表明,分段填充方法可以有效的形成沿同一方向传播的爆震波；详细分析了内部流场结构,旋转爆震波会使流场呈现周期性变化,斜激波和接触间断面是造成流场在出口平面波动的主要原因。旋转爆震发动机具有较高的比冲,基于燃料的平均比冲为49131.5 N·s/kg。 

Abstract: A reduced kinetic mechanism based on 19-step reaction and 9 species for mixtures of 2H₂₊O₂₊₄N₂ was used to simulate two-dimensional rotating detonation engine. The transport processes such as thermal conduction, diffusion and viscosity were omitted in the study. A method of piecewise fill was used to initiate rotating detonation wave. Results show that the method of forming detonation wave along one direction propagation was effective. Detailed analysis was given. Rotating detonation wave can make the flow field change periodically. Oblique shock wave and contact discontinuity are the main reason of flow field fluctuation at exit plane. Rotating detonation engine has high specific impulse and the fuel-based average specific impulse is 49131.5 N·s/kg.
