It is important to estimate corrosion environment of steel bridges for an appropriate corrosion prevention and maintenance program. Estimation of environment has heavily depended on insitu observation and many data have been collected. However, versatile numerical approaches to this problem have not fully been pursued yet. The objective of this work is to apply the method of computational fluid dynamics(CFD) to estimate the corrosion environment in a box-girder, where the boundary conditions are relatively well-defined and therefore numerical simulation is easily applicable. In the present analysis, water condensation on a girder-surface is considered by a simple but reasonable droplet modeling. The present CFD analyses rationally explain the relation between the inside and outside temperature and humidity, the location of condensation.
