| 摘 要： | 在菊花形混合器混合增强机理深入分析的基础上,采用环形流线流动模型、平板火焰扩散模型以及三维细长体近似法等,提出了涡扇发动机内外涵菊花形混合器在相同出口面积条件下,相对于环形混合器,其混合效率的解析解.对某涡扇发动机的多工况计算结果表明,菊花形混合器混合效率解析解的计算精度较高,可以用于菊花形混合器混合效率的快速计算.

| Abstract: | The analytical solution of the mixing efficiency of the lobed mixer,in relation to that of the splitter mixer in the same cross-section area of outlet,was proposed by using the circular streamlines model,the planar diffusion flame model and the slender-body approach etc.,based on thoroughly study of the mixing mechanism of the lobed mixer.Then,the mixing efficiency of a practical turbo-fan engine lobed mixer was calculated in four flying cases.The results show that this analytical solution method is reliabl... |
