A high-order, quasi-one-dimensional, reacting, compressible flow solver is developed to simulate non-ideal effects and chemical kinetics in shock tube systems. To this end, physical models for the thermoviscous boundary-layer development, area variation, gas interfaces, and reaction chemistry are considered. The model is first verified through simulations of steady isentropic nozzle flow, multi-species Sod’s problem, laminar premixed flame, and ZND detonation test cases. Comparisons with experiments are made by examining end-wall pressure traces that are gathered from shock tube experiments designed to test the code’s capabilities. Subsequently, the solver is utilized for uncertainty quantification and design optimization of a driver insert. Both applications prove to be highly efficient, indicating the utility of the solver for the design of experiments in consideration of non-ideal gas-dynamic effects.

StanShock：具有非理想效应和化学动力学的激波管模拟气体动力学模型

开发了一种高阶、准一维、反应、可压缩的流动求解器，用于模拟激波管系统中的非理想效应和化学动力学。为此，考虑了热粘性边界层发展、面积变化、气体界面和反应化学的物理模型。该模型首先通过稳态等熵喷嘴流动、多物种 Sod 问题、层流预混火焰和 ZND 爆炸测试案例的模拟得到验证。通过检查从旨在测试代码功能的激波管实验中收集的端壁压力轨迹，与实验进行比较。随后，求解器用于驱动器插件的不确定性量化和设计优化。这两种应用都被证明是高效的，
