摘　　要：喷管中跨声速流动的反应流体动力学是实验和理论研究的一个重要领域。本文主要由两部分构成,在第一部分中对文献[2]中的Murman格式[1]的一般形式进行了简化,得到了守恒形式的欧拉方程,并对其求解方法进行了讨论,同时针对Chattot等的工作展开了分析,并给出了带激波的流动计算结果;而文章的第二部分则研究了包含摩擦、加热以及耗散的跨声速流动,并重点关注了一步Arrhenius化学反应模型下的爆震现象。本文还探究了摩擦力和带燃烧的跨声速流动之间的相互作用,同时详细给出了新的欧拉方程数值求解算法并同已有文献算例进行了对比验证。The reactive fluid dynamics of transonic flows in nozzles is an important area of experimental and theoretical research.This paper consists of two parts.In the first part an algorithm for the solution of the Euler Equations in conservative form is discussed which simplifies a generalization of Murman Scheme [1] that is presented in Reference [2].Chattot＇s work is discussed and calculations for flows with shocks are presented.In the second part,transonic flows with friction,heat addition and dissipation is considered.Specific attention is given to detonations with one-step Arrhenius chemistry.A part of this study is to understand the interaction between friction and transonic flow with combustion.The details of the numerical algorithms will be presented along with validation examples from the literature.
