您要查找的是不是:
- fundamental blade passage frequency 桨叶基频
- blade passage frequency 叶片通过频率
- Blade passage meridional profile is obtained by solving a elliptic-curve equation, while the exducer is designed based on the cylindrical-parabola surface approach. 用椭圆曲线 的方法设计了子午面的型线,用圆柱抛物面的方法设计了透平叶轮的导轮的型线。
- The numerical results show that blade cutting causes the development of tip clearance vortices and blade passage blockages, which reduce the flow rate and the work done by the blade. 基于数值计算结果的流场分析表明,叶片磨短后叶顶间隙涡进一步发展,阻塞叶顶流道,使流量锐减,同时降低了叶片顶部区域做功能力。
- The dual time step procedure is used to simulate the unsteady flow through a one-stage compressor, and the result reveals that there are complex unsteady flow structures in the blade passage. 上游叶片排尾迹对下游叶片通道流动影响很大,它增加边界层损失,并在通道中与主流发生强烈掺混,最终使得出口流场及损失分布较为均匀。
