The Numerical Simulation Of Interaction Of Water Waves And Floating Structures In A Viscous Fluid

The interaction of water waves and floating structures is of considerable importance for the exploitation of coastal defense and oil-gas resource in ocean. For structures of large scale, based on the linear potential theory, there have many methods for solving such problems under the hypothesis of the small wave amplitude. However, the ability of the linear potential theory will be limited under the many cases, such as slamming and green-water. The numerical wave flume based on the viscous fluid theory will be a more effective and direct way to solve such non-linear hydrodynamic problems.On the basis of reviewing and summarizing the recent research progress of this subject, the work in the following aspects has been carried out:In Chapterâ…¡, based on the N-S equation, the VOF method is used to track the free surface, the additive sources in the momentum equation are used to generate and absorb waves, the method of waves generating and absorbing in the viscous fluid is presented. The 2D numerical wave flume which can both generate and absorb waves is obtained. The validity of waves generating and absorbing is numerically confirmed. The reflection and transmission of water...
