The performance of the centrifugal compressor at different diffuser stagger angles and different inlet guide vane ( igv ) prewhirl angles are measured 摘要对扩压器进口不同安装角和进口导叶不同预旋角匹配下离心压缩机的性能进行了实验研究。
Some of the air is used for cooling the turbine blades and nozzle guide vanes , and part of it is employed to cool and seal the turbine discs 在现代航空发动机中,从压气机引出的压缩空气一部分用来冷却涡轮叶片和涡轮导向叶片,另外一部分用来冷却和密封涡轮盘。
Prototype observation and model experiment indicate that flows in two channels of the discharge passage of an axial - flow pump and a guide vane mixed - flow pump are unequal to each other , there is flow deviation 摘要原型观测和模型试验都表明,轴流泵和导叶式混流泵双孔出水流道两孔流量不等,存在偏流。
The effects of layout of tip gap clearance on axial compressor rotor performance and stability have been investigated experimentally . a single - stage compressor rotor with no inlet guide vanes was tested under subsonic condition 本文用实验的方法对压气机转子尖部间隙沿轴向周向的布局进行了详细的研究。
Both the guide vane opening and blade opening of a hydropower generating unit can be separately regulated during disturbance according to the optimal regulation laws thus obtained to optimize the transient process of water flow 它可以使得在扰动下水轮发电机组的导叶与浆叶的位置按照各自的优化控制规律进行调整,从而使水力过渡过程达到优化。
