车用轴流涡轮叶轮间隙流动的数值研究

Numerical and Analysis of axial turbine Used for Vehicle

应用数值方法对设计的车用燃气轮机的轴流涡轮结构及性能影响作了分析,研究位置分别为叶尖、叶中、叶根。计算结果表明:轴流涡轮是在亚音速流场内工作,没有激波产生,也没有不合理的流动现象和很大的流动损失,它能较好地运转在工况点上。

With the numerical methods,the axial flow turbine’s structure and properties is analyzed,the study locations are the tip,the middle,and the root.The result shows that:the axial turbine is working in subsonic flow field and produces no shock,no very unreasonable flow phenomena and large flow losses,it is better to run on the operating point.
