Abstract
Physical model tests are traditionally used in engineering practice to study
hydraulic problems related to dam and spillway structures. Thanks to its rapid
development during the past few years, numerical technique has been adopted to
replace model tests in solving some of the hydraulic problems. In a R&D project,
the CFD program STAR-CD is employed to simulate the discharge capacity of a
standard WES spillway. Experiments are made separately to verify the numerical
results. The agreement between the numerical simulations and experiments
proves to be generally good. STAR-CD can reach the same order of accuracy as
a model test usually can. With the technique Embedded Mesh Refinement, the
CPU time can be significantly shortened. The study has shown that CFD has
potential and is a useful too
