With the upstream water level reducing and the downstream water level increasing, the highest tangent velocity also moving to the pipe center.
随上游水位的降低及下游水位的升高,切向流速最大值点也不断向管中心一侧移动。
The bigger the downstream water level, the outstanding of variation degree of axial velocity along radius distribution when upstream water level is same.
下游水位越高,变化相同的上游水位时,轴向流速沿径向分布的变化程度越大。
A barrage would halt the flow upstream and lift the water level.
一道拦河坝将会在上游拦住水流,抬升水位。
