| 摘 要： | 论述了某型号涡扇发动机带甩油盘燃烧室从建模到流场计算的整个过程，对半折流式环形燃烧室进行了冷态流场三维流动数值模拟，运用先进的数值计算软件，模拟甩油盘旋转甩油的过程，数值计算得到了燃烧室的速度场、总压恢复系数的分布以及燃油分布情况。为燃烧室的热态流场计算和燃烧室的设计、反设计及改型奠定了基础。

| Abstract: | The process of turbofan engine combustion chamber non reaction flow computation was discussed. Non reaction three dimensional flow in turning back flow annular combustion chamber was simulated. Velocity field,restoring coefficient of total pressure and fuel distribution were gained. It can be the fundament to compute reaction flow,design and counter design. It is also important to improve engine performance in the future. |
