NUMERICAL SIMULATION OF SEA SALT SPRAY BASED ON PRECISE CONSIDERATION OF WAVE AND WIND ACTION

Abstract

 Sea salt spray, which consists of small particles of seawater, harms long term durability of concrete structures at coastal areas due to its generation from the interaction of sea waves and, wind. In this study, a comprehensive numerical scheme in which waves, wind, and sea salt spray generation and transport mechanisms coupled together, is proposed with a wide range of applicability to real structures problems. Field measurements were also carried out to confirm the validity of the numerical results. Furthermore, through the numerical scheme a numerical model that can treat generation and transportation of sea salt spray considering coastal waves and atmospheric winds was proposed. It was confirmed that numerical results of sea salt spray concentration agree with the filed measurements data. Long-term sea salt spray distribution affected by waves and wind condition was estimated by the computational scheme of sea salt spray of this work.
