A note on withdrawal from a fluid of finite depth through a point sink
| ||||||||
| ||||||||
| Abstract | ||||||||
| The problem of withdrawal through a point sink
of water from a fluid of finite depth with a free
surface is considered. Assuming the flow to be
axisymmetric, it is found that there is a maximum
Froude number at which such flows can exist.
This maximum corresponds to the formation of a
secondary stagnation ring on the free surface.
This result extends earlier work on this problem.
Comparison is made with a small Froude number
solution and past experimental results.
