Abstract
The free-surface flow under a sluice gate is considered. The
fluid is assumed to be inviscid and incompressible. The problem is
solved numerically by using a boundary integral equation technique.
Accurate numerical solutions are obtained when the intersection of
the upstream free surface with the gate is a stagnation point. It is
shown that the radiation condition is not satisfied far upstream and
that there is a train of waves on the upstream free surface. For
large values of the downstream Froude number F, the
amplitude of the waves is so small that the upstream free surface is
essentially flat. However for small values of F, the waves are
of large amplitude. They ultimately approach the Stokes'
limiting configuration with an angle of 120° at their crest as
F is decreased.
