Abstract: The air distribution of the scrapped ammunition destroyed workshop is numerically simulated using FLUENT software based on the standard κ-ε two equations turbulence model and SIMPLEC pressure-speed coupled algorithm; then the particle distribution of the scrapped ammunition de-stroyed workshop is numerically simulated by the discrete phase model of FLUENT after the air flow field calculating convergence. Finally, the results of numerical simulation are analyzed. The results show that changing supply air speed has little influence for the air distribution of the workshop and some regional air flow is easy to form dead zone in the existing supply and back air form. Under the same conditions, small size of particulate easily spreads to the top of workshop and higher level, but large size of particulate does not easily spread to the top of workshop, and the concentration of the particle is higher in certain areas of the workshop. The optimizing advices are put forward for the ventilation system designing of the scrapped ammunition destroyed workshop based on the results of numerical simulation.
