A two-or three-dimensional compressible, Reynolds-averaged, Navier- Stokes hydrocode using adaptive zoning and finite-volume TVD differencing called MAZ for Multiphase Adaptive Zoning was used to simulate the formation of radioactive nuclear dust clouds. A series of sensitivity studies examining the effect of changes in particle agglomeration and radioactive vapor condensation models on the activity particle size distribution APSD were performed. In addition, a model which accounts for the effect of turbulent fluctuations on the radioactive vapor condensation process was implemented and tested. Accounting for agglomeration of wet particles was found to have the single largest effect on APSD. Microphysics, Nuclear dust cloud, Radioactivity, Numerical simulation, Turbulence model.
