A 3D Numerical Model for Free Interfacial Flows and Applications to Offshore Waves with Submerged Obstacles

Abstract:

A 3D numerical model for incompressible multi-fluid flows has been developed by using a multi-moment finite volume method and an accurate and efficient VOF type scheme for capturing moving interfaces of multi-fluids. The numerical model is validated with the theoretical and experimental results of the benchmark tests of solitary wave and dam break flow, which indicates the adequate numerical accuracy of the model as a practical tool to assess and predict offshore waves and their impacts on coastal structures. Numerical experiments have been systematically conducted to investigate wave breaking phenomena and the impacts on seawalls.
