The Los Alamos National Laboratory has performed experiments and modeled airflow patterns in Room 3305 of Building 371 at DOE's Rocky Flats Plant. Knowledge of the airflow movement and ventilation rates in the plutonium-handling rooms will allow proper placement of alarms and detectors to increase worker safety. Room 3305 is complicated; it features multiple airflow inlets and outlets and complex geometry with multiple obstructions such as gloveboxes, ductwork, and other obstacles. The purpose of this study was to determine whether a Computational Fluid Dynamics (CFD) model of Room 3305 was feasible and whether it would yield reasonable results when compared with a limited number of experiments performed in Room 3305. A model consisting of approximately 27,000 cells, 10 air supplies, 14 exhausts, 5 variable-sized gloveboxes, and miscellaneous obstructions was constructed. This information was input to the finite-difference, transient, three-dimensional CFD computer code SOLA-DM.
