Evaluation of Three-Dimensional Environmental Hydraulic Modeling in Scour Hole

The main goal of this study was comparing the performance an open-source code OpenFOAM and a commercial software Ansys Fluent in simulating turbulent flow through scour hole developed sand bed channel, which helps to give hint choosing appropriate calculating tool. Both models were set with same mesh as similar possible numerical settings, RANS turbulence modeling, applying k-?SST model, transient simulations. results pattern, velocity, properties collected compared laboratory experimental data. analyzed showed that, although both two cannot perfectly reproduce values from experiment, they can quite well capture near wall, bit higher coming model application.
