The inlet flow angle and diviation angle were confirmed which was applied to low cascade experiment result of American NACA, and controlled diffuser factor and flow deflection angle in design.
并应用美国NACA低速叶栅试验结果确定流入角和落后角，设计中控制扩散因子和气流折转角。
The results show us that, the deflection of the air flow direction has the linear relationship with the baffle installation angle;
结果表明，加装挡板后气流方向的偏转与挡板安装角度有一定线性关系；
