涡轮导向叶栅内流动的数值研究

Computational Investigation of the Flow in Turbine Guide Vane

为了有效地区分各种损失对涡轮总效率的影响,准确把握涡轮叶栅流场气动性能,对某型涡轮导向叶栅内的气体流动进行了数值模拟。结果表明,对此涡轮导向叶栅的改型设计比较成功。

In order to distinguish the different affections of the total efficiency of the turbine by different losses, and investigate the aerodynamic character of the turbine cascades, the computational investigation was applied on some type turbine guide vane. The results showed that it is successful of the redesign to the guide vane.
