Abstract
This study aims at investigating the effect of the expanded
transitions on flow characteristics .
In the theoretical study, dimensional analysis was employed
to relate the different factors affecting the phenomena.
Moreover,
the momentum principle as well as the continuity
equation were used to get an expression for the recovery in
water surface elevation in the expanding transition.
Experiments were conducted in a smooth rectangular channel.
Models with different diversion angles and expansion ratios
were tested using variables flow parameters, i.e. discharge, and
tailwater depth.
Using
the experimental
data, relations were plotted
describing the main characteristics of flow.
For analysing the
experimental data statistical methods were used to
empirical formulae for the main characteristics of flow .
