Abstract
This paper deals with scour around a circular pile exposed to a
steady current. A 3D numerical model incorporated with the k-w,SST
closure coupled with the sediment-continuity equation and a
bedload sediment transport formula has been used to predict the
scour. 3D calculations have also been carried out for a plane
rigid bottom for reference purpose. The predicted flow features
are apparently in fairly good agreement with the experimental
data. Early calculations indicate that the model is able to
predict the scour properties satisfactorily in the initial stages
of the scour process, up to scour depth of 0.6-0.7 times the pile
diameter. Calculations that describe the entire scour process
(including the equilibrium stage) are underway.
