摘要
综合分析了影响脱流特性的因素,运用所开发的程序,计算分析了改变叶根设计反动度、径高比和静叶片出口几何角对末级脱流的影响.提出了改善脱流特性的措施,供设计参照.
Factors influencing flow separation characteristics are analysed in general. Effects of varying design reaction at blade root, radius to height ratios and nozzle exit angles on flow separation in last stage blades are investigated by using a self-developed program. Finally, some methods of improving separation characteristics are suggested for design reference. Figs 6 and refs 6.
