Abstract

Predicting the scour around different structures built in the rivers using numerical models is always of high significance for researchers and designers. Since the groyne was one of these structures for accounting the rivers in this study, it has been attempted to anticipate the scour around the open groyne using the numerical simulation. Because the turbulence models in software is of high concern, therefore, in this study, different turbulence models have been used in Flow-3D software and compared with experimental results. Then, the best turbulence model which is successful in accounting the amount of maximum scour and location of this amount acted. was introduced. In the following, by changing the opening of groyne, vortices caused by numerical simulation, in section of groyne installed was shown. Then changes in cross-flow power and vortices caused by cross-flow power, in different cross section examined for open and close groyne with different percentage of opening.
