Simulation of fire development in a large-area shopping hall

[摘要] The results obtained after numerical simulation of fire development in a large area shopping hall are presented and widely discussed. The analysis has been conducted for two types of halls differing in size and efficient ventilation capabilities. A fire development scenario has been forecast under the assumption that a sufficient number of smoke vents had been installed as required by the provisions of law. The obtained results have been related to the hypothetical case where there were no smoke vents whatsoever. The stacking height of the merchandise gathered in the hall has been differentiated during the analysis as well. The numerical simulations have been performed with application of the FDS computer program. It has been assumed, that the fire had been initiated by a single source uniquely defined and initially limited in spatial area of influence. The results obtained indicate that the spatial and temporal fire development is different for each of the considered scenarios. The key role of the possible limitations in the exchange of gases between the area affected by fire and the environment, influencing the way and speed with which the fire propagates, has been confirmed during analysis.
