Structure-Water Surface Interaction

Understanding the interaction between a water free surface and a structure is important for many applications in naval, ocean and coastal engineering. Two topics in this area will be discussed. The first topic is the impact of breaking waves on a vertical wall that does not reach the seafloor. Through a comprehensive experimental study, three impact regimes, which are based on the interaction between the wall's bottom edge and the wave, were discovered. The characteristics of each regime will be introduced. The second topic is the controlled slamming of rigid/elastic plates on a water surface. The study aims at providing physical insights into strongly coupled fluid-structure interaction processes during hull slamming events, such as in planning boats or amphibious aircraft operating at high speeds. A very recent experimental study on this complex interaction will be presented. The experiments incorporate a fundamental configuration and highly controllable experimental conditions to allow the detailed investigation of the physics. The novel experimental facility and instrumentation will be introduced and several features of the experimental setup will be described. Some interesting results as revealed from the ongoing analysis of the data will also be presented.


Dr. An Wang is currently a postdoctoral researcher at the Hydrodynamics Laboratory at the University of Maryland. He received his B.E. in Naval Architecture and Ocean Engineering from Shanghai Jiao Tong University. He received his M.S. and Ph.D., both in Mechanical Engineering, from the University of Maryland, College Park. In his research, Dr. Wang primarily uses various experimental methods to explore fundamental problems in areas such as free surface flows and fluid-structure interactions, with applications in naval architecture and ocean engineering. In particular, he recently investigated the impact of breaking waves on partially submerged walls and the fluid-structure interaction during controlled slamming of flexible plates on a quiescent water surface.
