Abstract

The Setting Test (MUST) experiment, that was carried out at Dugway Proving Ground, was analyzed using Very Large Eddy Simulation (VLES). The CFD approaches used to simulate transport and dispersion in the atmosphere at the urban scale included Reynold Average Navier-Stokes (RANS) and LES. Improvements of the vertical turbulence production were introduced using the geometrical roughness applied to the ground surface. The results show that small changes in wind direction can produce large localized changes in concentration levels.
