The fire field model Fire Dynamics Simulator (FDS) version 3.10 was used to predict the rise times of free, wall, and corner buoyant plume fronts in this paper. The numerical simulation results were compared with those obtained from fullscale burning tests conducted earlier in the PolyU/USTC Atrium, in which the smoke plume fronts were measured by indicator lights and gauge. It is found that the rise times of the smoke plume fronts predicted by FDS are slightly shorter than the experimental values.
