Three-Dimensional Flow Simulation Research on Spur Dike

A three-dimensional (3D) flow mathematical model has been applied to simulate the flow field around spur dikes. In the vertical plane, the z-coordinate was adopted, and the additional layer was used to track the free water surface. The standard k-ε model was adopted, additionally, wall function and large coefficient method was applied to treat the boundary of the spur dike. Simulated results of velocity distribution, turbulent kinetic energy and its dissipation rate around the spur dike agree well with the experimental data.
