Equation of new type of cylindrical blade with adjustable wrapping angle of centrifugal impellers;
离心泵可控包角圆柱形叶片型线方程
The authors of this paper establish 3D models for several typical cylindrical blades using UG technology.
圆柱形叶片广泛应用于低比转速叶轮,本文作者以UG技术对常用的圆柱形叶片进行了造型,从而有利于帮助设计人员及时、直观地发现叶片的水力特性和机械特性,可以看出将UG技术引入叶片水力设计领域,将对提高叶片性能产生积极的重要影响。
When a cylindrical fragment is in the air,it is discovered that windward area is stochastic,so the figure modulus of the cylindrical fragment is not single but variable in a range.
当圆柱形破片在空中飞散时,迎风面积随机变化,导致圆柱形破片的形状系数不再是单一的值,而是一个范围,因此必须对已有的圆柱形破片的形状系数进行修正,才能更准确的预测圆柱形破片在空中的速度衰减。
