| Popis: | 101 This research includes FDS simulation and experiment, compare the impact of a fire and FDS software source set of the fire and fuel type parameters for discussion, and simulation experiments are compared with the Scale model, Simulation scale model and and experimental comparison. Reference laws and regulations set building exhaust equipment, observe and compare the FDS model at different scales changes in smoke and facilities of mechanical exhaust and stairway pressurization system were employed to compare their hazard reduction effect. Simulation results indicated FDS at different scales heat release rate changes, in the different scale reaches the set value after stable. FDS simulation average heat release rate each scale maximum error of -0.35%, the heat release rate of the simulation results of the heat release rate and stability compared to the set value, the maximum error of about -0.43%. Simulate different model scale smoke dynamics and changes in visibility conditions, simulation results indicated that both smoke dispersion similar to the situation. In the follow-up study to compare adding facilities of mechanical exhaust and stairway pressurization system effect, simulation results indicated stairway pressurization system can enhance visibility well in not hinder evacuation personnel. this system can help firefighters rescue and personnel evacuation. |
