速度剖面 velocity profile
- 所有的颗粒都降低了射流速度半宽,但对流向平均速度剖面的影响比较复杂。
All particles reduce the jet velocity half-width, but the effects on the streamwise mean velocity profiles are complicated. - 利用速度剖面公式计算的垂线平均流速场与实测值符合较好。
The dimensionless velocity-profile formula fits not only the depth average velocity profile but also velocity profile of each layer along depth. - 结果显示,颗粒的流向平均速度剖面呈高斯分布,而横向平均速度剖面则呈正弦分布。
The results show that the streamwise mean velocity profile of particles takes on a Gauss distribution, and the lateral mean velocity profiles assumes a Sine distribution.
