Numerical simulation of shallow water waves around coastal structures by a chimera potential-flow method
Additional Document Info
A three-dimensional potential flow numerical method was developed for the study of wave reflection, diffraction, and refraction around complex coastal structures. The method solves the Laplace equation for unsteady body-wave problems using a chimera domain decomposition approach. It has been used recently in Chen and Lin (2000) for time-domain simulation of wave diffraction problems around a harbor entrance, a single breakwater, and a combined breakwater and large floating platform to illustrate the flexibility and effectiveness of the method. In the present study, the chimera Laplace method was further extended for the computations of wave reflection, diffraction, and refraction around a straight channel inlet and an elliptic shoal. The numerical results were compared to the analytic solutions and experimental data to provide a thorough validation of the chimera Laplace method.
