Investigation of Effect of Blade Vortex Distribution on Backswept Impeller Performance in Aerodynamic Design

背掠式离心转子设计中叶片涡分布对其性能影响的研究

Comparison with available experimental data was made for three different impellers: backswept log-spiral blade, straight radial blade, and curved blade with backward sweep. Good agreement was obtained for the streamline and velocity distributions.

就三种不同叶片的叶轮后掠式对数螺旋线叶片，直线径向叶片，后掠弯曲叶轮比较它们已有的实验数据，流线与速度的分布基本相同。

An experimental investigation of the shrouded centrifugal backswept impeller flow field has been conducted at off-design flow using Laser Doppler Velocimeter ( LDV) and shaft encoder.

利用激光多普勒测速仪（LDV）对后弯闭式离心叶轮内部气流在非设计工况下的流动进行了实验测量。

He made a quick drop , slanting down on his backswept wings, and then circled again.

它倏地斜着后掠的双翅俯冲, 然后又盘旋起来.

His long, backswept hair, dyed black since the age of 16, frames a face that has been described both as "angelic" and "hideous to the eye," the latter by Cave himself, in song.

他的长发向后梳去，自从他16岁后就总是染成黑色，衬托他那张既可以描述为“天使一般”，也可以描述为“看上去很丑”的面孔——后一个是凯夫自己在一首歌里唱的。
