Simulation of Particulates Resuspension from Human Walking in UFAD Room

Abstract:

In this study, the Lagrangian method is used simulate a process of particles resuspending from occupant walking and being carried away by exhaust in a under-floor air distribution (UFAD) room. Experiments are performed in the prototype of the model room, the results confirmed the particles concentration decay tendency. On the other hand, the numerical simulation results for time of decontaminate the particulates in indoor is agreement with the experimental results. It indicates that the Lagrangian method is suitable for calculate such a process. Based on these studies, the following conclusions can be obtained: (1) human walking cause the particles above 5μm increased rapidly by which resuspended into indoor air; (2) the particles can removaled by exhaust quickly, and it will not cause a long term effect.
