中文摘要:
      为了研究旋转爆轰燃烧室几何结构对旋转爆轰波的影响规律,针对旋转爆轰燃烧室高度对爆轰流场结构和爆轰波传播 特性问题,采用2 维数值模拟方法分析了爆轰波在4 种高度的燃烧室内的参数变化和波系特征。结果表明:在4 种高度的燃烧室内 爆轰波均能自持传播,且爆轰流场结构相似;当燃烧室高度为4 mm 时,爆轰波后的反射激波压力较高;在一定范围内,爆轰波传播 速度随燃烧室高度的增加而增大,在爆轰波高度为10、16 和20 mm 时,爆轰波波锋面的压力分别为3.93、4.61、4.69 MPa。
英文摘要:
      In order to study the influence of the geometric structure of the rotating detonation combustion chamber on the rotating detonation wave,the parameter variation and wave system characteristics of the detonation wave in the combustion chamber at four kinds of heights were analyzed by using the two-dimensional numericalsimulation method forthe structure and propagation characteristics of detonation wave in the rotating detonation combustion chamber. The results show that the detonation wave can propagate by itself and the structure of detonation flow field is similar. When the combustor height is 4 mm,the reflected shock wave pressure after detonation wave is higher. Within a certain range,the detonation wave propagation velocity increases with the increase of combustion chamber height. When the detonation wave height are 10 mm,16 mm and 20 mm,the detonation wave front pressure are 3.93 MPa,4.61 MPa and 4.69 MPa,respectively.
