Full-Scale Experimental and Numerical Study on Combustion Behavior of Upholstered Sofa in ISO 9705 Room

摘要

In this paper, full-scale fire tests on upholstered sofa were conducted in the ISO 9705 room (3.6mx2.4mx2.4m). Parameters such as heat release rate of sofa, temperature fields of ceiling and doorway in the room were recorded, relationship between heat release rate and upper-layer temperature was discussed. Meanwhile, numerical simulation methods were applied to simulate combustion behavior of the upholstered sofa, which was dominated by the burning of PUF materials. The calculated data of heat release rate, temperature fields and hot/cold smoke layer heights were compared with experimental data. The results were reasonable and comparison between simulation and experiment was fairly good and promising.
