据观察，一个接口建立在任何开放式的垂直圆柱体时，羽流的方向上的平均流动通过圆柱体。界面的位置决定了羽流的体积通量，因为环境中的总排放量已被夹带在这一水平。已经进行了实验，以验证这种关系，并定义在其中建立的接口的限制。据发现，随着羽流浮力的减少或环境面积的减少，限制确实存在。介绍了该接口在工业建筑通风中的应用。
It is observed that an interface is established in any open-ended vertical cylinder when a plume flows in the direction of a mean flow through the cylinder. The location of the interface defines the volume flux of the plume because the total discharge in the environment has been entrained at this level. Experiments have been conducted to verify this relation and to define the limits within which the interface is established. It is found that, as the buoyancy in the plume is reduced or the area of the environment is reduced, limits do exist. An application of the interface in industrial-building ventilation is described.
