For simulating the radial static pressure gradient behind the true turbine guide cascade in low speed wind tunnel with annular cascade, the backboards were placed in the downstream field of the guide model cascade of the low - pressure stage of a turbine, and the effects of the types and positions of the backboards on the outlet flow field of the model cascade were experimentally researched
為在環形葉柵低速風洞實驗中模擬實際渦輪級靜葉后徑向壓力梯度，在某型渦輪低壓級靜葉的下游流場設置了擋板，實驗研究了擋板形式及設置位置對靜葉出口流場的影響。 -
In this dissertation, a hybrid optimization approach for automatic design of 3d turbine blades was proposed and well implemented. the applications to the stacking design optimization and full 3d aerodynamic design optimization for an annular cascade demonstrated the validity, robustness and efficiency of this hybrid approach
