Abstract
This study aims at investigating the characteristics of
the submerged and free hydraulic jumps in abrupt expansions.
In
app 1ied
the
theoretical
study,
dimensional
analysis is
to relate the different
factors affecting the
hydraulic
phenomena. Moreover, the momentum principle as
well
as the continuity equation are used to get some
expressions
defining
the relations between
the main
characteristics of the flow and the hydraulic jump.
Experiments are conducted .in a smooth rectangular
channel.
Models with different expansion ratios are tested
using variable flow parameters,
i.e. discharge, and
tailwater depth.
Using
the experimental data, verification is made for
the theoretical expressions. For analysing the experimental
data statistical
methods are used
to deduce empirical
formulae for some characteristics of flow. Relations are
discussed using the different hydraulic principles.
Finally, practical
applications are introduced to
connect the laboratory experiments with field work.
