用反应动力学松弛模型研究了双分子化学反应气体混合物中的激波结构。在一维空间中数值求解相应的非线性积分-微分方程组，上下游渐近平衡条件满足反应性Rankine-Hugoniot关系和熵条件。给出了数值结果，强调了马赫数、上游浓度分数和激波化学成分变化的作用。
The shock structure in a gas mixture undergoing a bimolecular chemical reaction is studied by means of a reactive kinetic relaxation model. The relevant nonlinear integrodifferential equations are numerically solved in one space dimension with upstream and downstream asymptotic equilibrium conditions satisfying the reactive Rankine–Hugoniot relations and entropy condition. Numerical results are presented, emphasizing the role of Mach number, upstream concentration fractions, and change in the chemical composition across the shock.
