The corrosion rate of metals exposed to the atmosphere is mostly influenced by factors such as the deposition rate of marine aerosols, the deposition rate of pollutants such as SO2, and on relative humidity. The
transport and deposition of aerosols are subject to mass transport laws such as convection and turbulent difffusion. Based on these principles, the pattern of aerosol surface deposition was modeled near an obstacle that was about the size of a small shed (3m by 2m). The pattern of aerosol deposition onto simulated salt candles surrounding the obstacle was also modeled. The aerosol source was near the ground in order to simulate the edge of an ocean or salted road. The highest rate of surface deposition was in the middle of the back, then in the middle of the top and then along the front of the obstacle. There was only a loose correlation between the patterns of surface deposition and nearby salt candle deposition. Keywords: aerosol surface deposition, aerosol transport, atmospheric corrosion pattern
