| Research Abstract |
It is important to estimate corrosion environment of steel bridges for a proper corrosion prevention and maintenance program. Adhered sea-salt particulate matter(SSPM) is an influential factor especially in coastal areas. To this end, it is better to know the adhesion behavior of SSPM to bridge girders. The objective of this manuscript is to pursue numerical method to simulate the adhesion behavior of salt particles oriented from sea surface. Specifically, two scale approach is proposed. Mesoscale Meteorological Analysis and Lagrangian type two phase flow analysis are used in global and local analyses respectively. The comparisons between the numerical and observed results showed that the numerical analysis can reproduce essential behaviors of airborne SSPM
