Pouring Flow

摘要

Free surface flows of a liquid poured from a container are calculated numerically for various configurations of the lip. The flow is assumed to be steady, two dimensional and irrotational, the liquid is treated as inviscid and incompressible, and gravity is taken into account. It is shown that there are flows which follow along the under side of the lip or spout, as in the well-known teapot effect, which was treated previously without including gravity. Some of the results are applicable also to flows over weirs and spillways. (Author)
