| 摘 要： | 对超燃燃烧室的高速流动与燃烧的耦合流场进行了一维和三维数值模拟，揭示了其流场的本质和各个参数的关系。首先阐述了超燃燃烧室一维流动特性，然后分析了一维流动模型，获得了芯流面积的计算公式。将一维流动模型应用到实际超燃燃烧室中，与试验数据对比，误差小于5％，并且选出了最优模型。由于一维模型仅能模拟轴向的一维参数变化规律，不能...

| Abstract: | The 1D and 3D numerical simulations of the coupled flow field with high-speed flow and combustion in a hypersonic combustion chamber are carried out,by which the flow nature and the relationship between parameters are enunciated.The characteristic of 1D flow field in the hypersonic combustion chamber is elaborated.The one-dimensional flow model is analyzed to obtain the formula of the core flow area.The one-dimensional flow model applied to the actual supersonic chamber was compared with the experimental da... |
