| Abstract: | Based on the open source software, OpenFOAM, and dynamic mesh method, a mathematical model for the local scour of offshore wind turbine foundation is developed using the principle of equilibrium of bed shear stress. The model is applied to simulate the flow and local scour around circular pile foundations. The simulated results of flow and scour depth agree well with the experimental data. |
