Numerical Simulation of Wind and Sea Salt Particle Transport using Reynolds-averaged Turbulence Model - Estimation of Spatial Distribution of Cumulative Airborne Sea Salt -

Abstract

Numerical simulation of wind and sea-salt particle transport was performed using a Reynolds-averaged turbulence model. Spatial distributions of time-averaged airborne sea salt locally varied under the influence of complex terrains and ground surface roughness with decaying tendency according to the distance from shoreline. In comparison between observational value of deposited sea-salt and numerical value of airborne sea-salt, they showed significant correlation with each other except for points very close to shoreline, suggesting that this simulation technique has a capability to appropriately estimate the spatial distribution of deposited sea-salt and airborne sea-salt, though there is still room for improvement in inlet boundary conditions on the sea for better estimation of sea salt near shoreline.
