- 摘要:
- 空气泄入式扩压器是发动机高空模拟试验设备，扩压器内流场情况是评价扩压 器性能的重要依据。使用CFD软件分析计算了三种不同空气间隙(0mm，lOmm，20mm)的 扩压器模型。得到了不同间隙下扩压器内流场压力、温度等参数的分布情况。探讨了发动机 喷管偏心对扩压器内流场造成的影响。计算结果与试验数据相吻合，证明扩压器模型正确。
- Abstract:
- traet：The air leaked—in diffuser is a key equipment of the attitude simulation test of a kind of rocket engine．The internal flow field is an important basis for the diffuser performance assess— ment．Three kinds of diffuser models with different air clearances(0mm，10mm，20mm)were ana— lyzed and computed based on the Computational Fluid Dynamics(CFD)software，and the pressure parameters distribution and the temperature parameters distribution of the internal flow fields of the diffuser at different clearances were obtained．Tests show that the computational fluid dynamics analvzing results of the diffuser flow field are in good accordance with those of the tests，the diffuser model is correct．The influence of nozzle off—center on the diffuser flow field is alSO studied．
