Abstract

In order to operate the efficient maintenance and management, it is important to predict the amount of sea salt particles adhered to each member of a structural surface. In this study, two different method s of the deposition to a structural surface are discussed. One focuses on the sea salt concentration flux normal to a structural surface. Another one is based on the physical behavior of each sea salt particle. Using these models, the amount of sea salt particles on each member of a structural surface is predicted with the meteorological observation data. While the tendency of distribution is in good agreement between the predicted and the observed value, there needs further improvement to get more accurate results.
