| 摘 要： | 基于三维可压缩RANS方程，结合有限速率化学反应模型，发展了一套模拟多组元化 学 反应与湍流流动的计算程序。通过对超燃冲压发动机燃烧室内的几种典型流动问题，如横 向喷流问题、后向台阶流动问题和氢／空气化学反应问题进行数值模拟，验证计算程序的可 靠性，将数值模拟结果与实验结果进行了对比，结果吻合较好。

| Abstract: | A CFD flow solver modeled by 3D compressible RANS equations and finite rate chemical reaction model was developed for solving the multi-specie chemical reaction and turbulence flows.Numerical simulations were performed for the typical flowfields in scramjet combustor to validate the program,such as supersonic slot injection flow,supersonic flow over a backward-facing step and supersonic mixing and combustion of hydrogen in a 3d combustor.The CFD results were compared against the available experimental data and showed good agreement. |
