摘要
通过三类低展弦比涡轮叶栅气动参数的详细测量与壁面 (包括上、下端壁与叶片表面 )流动显示 ,研究了叶片弯曲降低能量损失的机理。实验结果表明 :在不同叶栅几何参数下 。
Through a detailed measurement of the aerodynamic parameters of three low aspect ratio turbine cascades and wall surface (including upper and lower end wall as well as blade surface) flow display the authors have studied the mechanism of energy loss reduction for curved blades. The test results indicate that under geometric parameters of different cascades a successful selection of the form of curved blades is dependent on the appropriate matching of the vortex magnitude field and expansion magnitude one in the cascades.
