A numerical approach for determining equilibrium scour depth around a mono-pile due to steady currents

摘要

In this work, we propose a first approximation approach to obtain the equilibrium scour depth around a mono-pile using a numerical scour model. This is achieved by modelling the turbulent flow around the cylindrical pile to obtain the bed parameters driving the sediment motion. Using the bed parameters obtained and a Torczon optimization algorithm, the simulation model attempts to deform the bed boundary towards the equilibrium scour depth in the shortest path possible. The predicted scour depth from simulations using this approach correlated reasonably well with experimental observations. (C) 2016 Elsevier Ltd. All rights reserved.
