Abstract: Accurate modeling and simulation of enclosure fire and smoke spread is always a challenge due to the various combustion materials and their complex chemical properties. To tackle this issue, a model of a furnished room and its connected corridor was developed by Fire Dynamics Simulator (FDS) and calibrated using the test results that were reported by the National Research Council Canada to analyze the toxic hazards from smoke. In FDS, a fuel package with combined properties of polystyrene, polyurethane, and wood was employed to simulate the combustion of the mixed burning items. The transient measured heat release rates were used in the fuel package. The combustion chemistry reaction model was also specified through a number of simulations to properly estimate the indoor conditions. Subsequently, the related curves of heat release rate, temperature, visibility, and smoke optimal density as well as CO and O2 concentrations match the test data.
