超音速混合层中的热反应形态分析

The analysis of reaction features in supersonic mixing layers

超音速混合层热反应形态的研究对于超音速燃烧过程和运载火箭底部热环境认识具有重要意义。基于耦合详细化学反应动力学机理的高精度数值模拟结果,分析了超音速混合层中的热反应形态。在处于不稳定燃烧和稳定燃烧两种状态下的混层中,结合组分的剖面分布,并采用Takno数和ZFO数,对超音速混层中热反应形态开展了研究分析。

The study of reaction features in supersonic mixing layer flows is of great importance for the understanding of supersonic combustion and base thermal environment of launch vehicle. Reaction features of supersonic mixing layers are analyzed based on results obtained by high-solution numerical methods with detailed chemical kinetics. Reaction features of supersonic mixing layer are studied combining not only profile distributions of component, but also distributions of Takno number and ZFO number.
