Abstract: In this research, the wave-induced mass transport and internal mixing during the focused waves passing a submerged breakwater are investigated numerically by an in-house code. A Liquid-liquid two-phase VOF method based on a multi-phase flow mathematical theory is proposed and implemented in a constraint interpolation profile (CIP) -based model. The free surface and water-water interface are simultaneously tracked under the Eulerian framework. The movement rules and mass transport characteristics under the focused waves passing a submerged breakwater are analyzed. Results show that the wave height of the focused wave group has a significant impact on internal mass transport and internal mixing during focused waves passing a submerged breakwater. All the results indicate the CIP-based model coupled with the two-phase VOF method can provide a different perspective to study the mass transport and internal mixing during wave-structure interaction in coastal engineering.
