Comparison of Rise Time of Smoke Plume Front Predicted for High Space by a Field Model with Full-Scale Experiments

摘要

The fire field model Fire Dynamics Simulator (FDS) version 3.10 was used to predict the rise times of free, wall, and corner buoy ant plume fronts in thispaper. The numerical simulation results were compared with those obtained from full-scale 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.
