| 摘要: |
| 为了获得以工程应用为背景的脉冲爆震发动机(PDE)模型可靠的性能评估方法,应用数值模拟与经验数据相结合的方法计算了某多管旋转阀PDE的性能。结果显示:采用动网格技术可以获得冷态填充过程中发动机的充填系数;结合煤油爆震的数据得到所设计的六管旋转阀PDE的平均净推力为827.8N。该方法融合了CFD计算和试验数据,为今后PDE性能估算提供了很好的参考。 |

| Abstract: |
| To obtain the credibility method of performance evaluating for the pulse detonation engine (PDE) for engineering applications.The numerical simulation and experimental data are used to get the net thrust of 6-tube rotary valve PDE.The results show that the engine filling coefficient in filling process of cold state can be acquired by dynamic mesh technique,the net thrust of 6-tube rotary valve PDE equals 827.8N using kerosene detonation data. |
