About

About the course

Course content

The course covers the underlying principles of numerical modeling of marine flows with complex free surfaces with a numerical wave tank. In the near-field, these types of flows occur under non-linear waves, where waves steepen up to and beyond the point of breaking. The numerical methods taught capture the complex free surface through two-phase flow modeling and solution of the three-dimensional Navier-Stokes equations. The numerical methods for the interface treatment, spatial and temporal discretization, parallel computing are presented. Essential parts of a numerical wave tank are the wave generation, wave absorption and the unique numerical aspects of simulating wave propagation. The relevant topics for marine and coastal engineering of modeling porous structures, floating bodies and sediment transport are also introduced. In addition, the possibility to use the two-dimensional depth-averaged version of the numerical wave tank is covered, which allows for large scale phase resolved wave modeling in conjunction with a non-hydrostatic pressure solution or additional dispersion terms. All numerical methods addressed in the lectures are implemented open-source hydrodynamics model REEF3D, which is developed at the Department of Civil and Environmental Engineering. A brief introduction of the object oriented principles and modular code structure of the numerical wave tank is given.
