ABSTRACT
This chapter presents the ship hydrodynamics model, a numerical scheme based on the Arbitrary Lagrangian Eulerian approach, solution approaches and results. Computational fluid dynamics (CFD) for ship hydrodynamics has been the subject of intense research in both scientific and industrial communities over the few decades. The ultimate goal of the computational ship hydrodynamics is to compute the behavior of flows around the ships and the motion of the ship. CFD approaches for free-surface and multiphase-flow problems can be classified into two main categories based on the kinematic approaches on calculating fluid flows: Eulerian approach, and Lagrangian approach. In the Eulerian approaches such as Front Tracking, Level Set, Volume-of-Fluid, Immersed Boundary, the model equations are solved in a fixed computational mesh, whereas the moving interfaces are tracked separately. The basic idea behind the front tracking method is to use separate front markers for the interface on a fixed mesh and modify the mesh near the front to fit the interface.
