Wall-slip velocity

The average sedimentary velocity under no-slip wall condition is largely less than that under periodic wall boundary condition.

固壁条件下多根椭圆粒子的平均沉降速度大大小于周期性壁面条件下的平均沉降速度。

The experimental results show that the radial profiles of local slip velocity are non-uniform :flat in the central region and steep in the region near the wall.

实验结果表明，提高颗粒循环速率，在任一径向位置的气固滑落速度均增加；

In the paper, the steady NS equation was solved to simulate aircraft roll by adding tangent velocity to no slip wall boundary condition.
