| Outline of Final Research Achievements |
Prevention of corrosion of steel structure is currently based on distance from the nearest coast. Concentration of airborne sea salt particles is overly simplified there. However, corrosion of structures is highly localized and authors have suggested importance to predict critical corrosive prone part using a proper CFD analyses. In such a CFD analysis, concentration of airborne sea salt particles is more important than usual quantities like by a dry gauze. The objective of this project is to establish a numerical method to estimate concentration of airborne sea salt particles at arbitrary location and time using a meteorological analysis. The accuracy of the analysis is verified by a year-long observation by a volume sampler. In the meantime, a relation between the results of a volume sampler and a dry gauze is also found. Captive ratio of sea salt particles barely depends on wind velocity.
