Abstract

Estimation of scour depth and understanding the flow field around pier would help to design with safer factor. In this study, we used the numerical model SSIIM as a CFD model to simulate flow and scour pattern simultaneously around single pier. The model was verified using laboratory data including the results reported for single pier. In this model, we considered the as a turbulence model to solve the 3D Navier-Stokes flow equations and used their outputs as inputs of sediment transition equations. Comparison between scour calculations of SSIIM model and experimental terms showed that the model has appropriate deviation value for estimating the maximum scour depth around single pier. Numerical and graphics discussions of scour pattern and flow field have been done in various simulation time for pier. Graphical results showed that the down flow at front of pier and upward flow at the rear of pier. In addition, the maximum down flow was simulated with high accuracy in compare with experimental results.
