管流管流是水力学及流体力学的分支，是指液体在管道的流动，且液体不存在自由表面（存在自由表面的类似流动称为明渠流）。 管流和明渠流有许多类似之处，但两者的差异主要是在是否有自由表面。管流没有自由表面，因此不会直接受到大气压力的影响，但是会受到管子内水压的影响。 不是所有在封闭管道内的液体流都属于管流，例如雨水排水道就是在封闭管道内，但多半存在自由表面，因此仍属于明渠流。唯一的例外是雨水排水道全满时，不存在自由表面，此时即可视为管流。

Pipe flow 管流Pipe flow, a branch of hydraulics and fluid mechanics, is a type of liquid flow within a closed conduit (conduit in the sense of a means of containment). The other type of flow within a conduit is open channel flow. These two types of flow are similar in many ways, but differ in one important aspect. Pipe flow does not have a free surface which is found in open-channel flow. Pipe flow, being confined within closed conduit, does not exert direct atmospheric pressure, but does exert hydraulic pressure on the conduit. |
