* Numerical codes were developed to solve the Reynolds-averaged Navier-Stoces equations for compressible reactive flows using the oxygen-hydrogen two-step or eight-step reaction model, and the k-epsilon or k-omega turbulence model. The codes were applied to the three-dimensional mixing and combustion flowefields for various parameters related the the scramjet engine combustors.* Supersonic combustion wind tunnel was constructed, in which the high temperature vitiated air is generated by the lean-bum combustion upstream of the test section. The temperature, pressure and the Mach number are compared with their disigned values. Ignition at the test section was confirmed by observation.* Experiments were conducted to establish the three-dimensional quantitative measurement technique by the laser induced fluorescence using the excimer laser and CCD camera systems. OH concentration in the correlation burner setup was successfully visualized. The numerical codes to calculate the equilibrium chemeical concetration were also developed. Further, the numerical codes were developed to calulate the axi-symmetric combustion flowfield, in which the mass diffusion terms are modeled properly.

* 开发了数值代码，用于使用氧-氢两步或八步反应模型以及 k-epsilon 或 k-omega 湍流模型求解可压缩反应流的雷诺平均纳维-斯托斯方程。这些代码应用于超燃冲压发动机燃烧室相关各种参数的三维混合和燃烧流场。*建造了超音速燃烧风洞，其中高温劣质空气由测试上游的贫燃燃烧产生。部分。将温度、压力和马赫数与设计值进行比较。通过观察确认了测试部分的点火。*进行了实验，建立了使用准分子激光和CCD相机系统的激光诱导荧光三维定量测量技术。相关燃烧器设置中的 OH 浓度已成功可视化。还开发了计算平衡化学浓度的数字代码。此外，还开发了数值代码来计算轴对称燃烧流场，其中质量扩散项被正确建模。
