摘要
针对自由涡轮导向器叶片可调的多级轴流涡轮进行气动性能研究。结果表明:通过改变自由涡轮导向器叶片角度可以调节多级涡轮的流量、效率、膨胀比分配和功率分配,自由涡轮导向器叶片角度变化对涡轮流场和各级静叶损失产生明显的影响。
The effects of the variable free turbine guide vane on the multi-stages axial turbine aerodynamic performance were investigated. The results showed that the mass flow, efficiency, expansion ratio allocation and power allocation of the turbine could be adjusted by changing the angle of the free turbine guide vane. The flow field and stator energy loss were also affected obviously by the angle of the free turbine guide vane.
