| Summary: | The ultimate objective of this study is the prediction of flow pattern associated with
spur dykes. Prediction of velocity fields and bed shear stresses were obtained using
the FLUENT package. The RNG k-eformulation in FLUENT has been validated
against selected benchmark solutions of flow in the vicinity of spur dykes. Extensive
testing procedures have been implemented to ensure that the equations and solution
algorithms used by FLUENT would provide an accurate simulation of flow.
Experiments carried out by Mayerle et al. (1995) and Zaghloul and McCorquodale
(1975) were selected as benchmark for verification purposes. FLUENT predicted
reasonably Iwell the attachment point downstream of the dyke in the flat-bed case.
Calculated bed shear stresses can then be used in appropriate sediment continuity
equations for the prediction of scour hole geometries |
