Abstract

In reality, the interaction between surface wave-current flow and numerous kinds of man-made maritime structures is local but embedded in a domain with the size of a sea. Detailed simulations of the vast domain are computationally unfeasible. Therefore, articial boundaries are introduced to truncate the large domain so as to obtain a small domain around the structure of interest. These articial boundaries can produce reections which obscure the flow information from true reflectors. To eliminate the reflections from articial boundaries, this thesis proposes absorbing boundary conditions (ABCs). The novelty is that ABCs for free surface waves in a detailed numerical model with a resolved vertical direction are derived in the presence of nonzero mean flow.
