Numerical Modeling of Flow Field in Morning Glory Spillways and Determining Rating Curve at Different Flow Rates
Abstract: Morning glory
spillways with drop inlets are normally employed in dams built on narrow
valleys or placed on steep slopes. In Iran, morning glory spillways have been
commonly used in large Dam projects such as Sefidrood dam, Alborz dam, and
Haraz dam. Physical models should be built to accurately determine hydraulic
parameters of the flow and flow field in spillways. Establishment of a physical
model involves extravagant costs and conditions that cannot be justified in
some cases. Therefore, suitable numerical models can be proposed for such
circumstances. Using FLOW3D numerical models, 3-dimensional numerical modelling
of the flow was calibrated and validated by experimental information associated
with morning glory spillway of Alborz dam and accuracy of numerical modelling
was determined by relative error of numerical model. So it was attempted to
determine flow pattern and control conditions of morning glory spillways in
different modes using boundary conditions, inlet conditions and grid spacing of
flow field and project rating curve of morning glory spillways. According to
the results of numerical model, relative error of numerical modelling equals
6.4% for calculating discharge rate of the spillways. Numerical modelling error
is 7.6% for determining depth parameter of the flow in spillway crest in
comparison with experimental results.
