Abstract
  • In this study, a coupled potential flow-viscous flow model is used for numerical wave tank simulation. The solver satisfies all the requirements for such a simulation environment. The coupling scheme is based on a non-overlapping heterogeneous domain decomposition method. In this method, the flow domain consists of two subdomains. In the potential flow subdomain, a boundary element method(BEM) is used to solve Laplace's equation, while in the viscous flow subdomain, a finite element method (FEM) is used to solve the Navier-Stokes equations(NSE). At the interface, velocity and pressure are used for matching conditions. Techniques for data transfer and local free surface reconstruction are also introduced. The same coupling scheme is further extended to incorporate the Reynolds-averaged Navier-Stokes equations by including an inner loop that solves, for instance, k-epsilon modeling equations and updates the eddy viscosity. The implementation based on staggered iteration method is validated using previous experiment and numerical data, for both 2D and 3D wave impact, wave--structure interaction, and wave breaking problems.
