Outline of Final Research Achievements |
Many concrete structures near shoreline receives salt damage by production and transportation of sea salt spray from sea surface. In this study, to discuss detailed sea salt spray of concrete structure surface, numerical schemes for production, transportation and accretion of sea salt spray was proposed. Calculation of transportation and accretion of sea salt spray was carried out on the condition which changed size of sea salt spray particle. Field measurements are also carried out to estimate amount of sea salt spray around the coastline in Niigata prefecture. In those results, a numerical scheme which can treat production, transportation and accretion of sea salt spray with coastal wave and atmospheric wind model was proposed. Production, transportation and accretion process of sea salt spray was showed by calculation results.
