Abstract
In the present paper, the results are explained for an experimental and numerical study on scouring phenomenon around a rectangular, impermeable and non-submerged bridge abutment cross section with perpendicular attitude to the flow axes. In this study, SSIIM 2.0 is used to simulate the scouring problem at the abutment. SSIIM 2.0 is a three-dimensional computational fluid dynamics program that uses a finite volume method to discretize the equations. According to the results, the k–e turbulence model with some RNG extensions is the best model for predicting turbulence around the rectangular abutment. In addition, different grids are compared in the simulations and the best grid is selected based on the accuracy of numerical results and the computation times. Finally, the findings are explained, and the bed changes and local scour profiles resulting from the numerical simulation are compared with the available experimental results. It is concluded from the achieved results that SSIIM 2.0 numerical modeling is capable of simulating scouring around a rectangular abutment.
