摘要：In the case of a fire incident such as arson, the combustion experiment that reconstructed the fire scene will be conducted to clarify the facts. However, various problems such as construction costs and securing an experimental environment must be dealt with. Therefore, the purpose of this study is to utilize fire simulation for the investigation of fire incidents. In this study, combustion experiments and FDS (Fire Dynamics Simulator) simulations assuming gasoline arson in the kitchen, which have not been reported so far, were conducted and compared. Next, the observation of fire damage using the accumulated heat-flux was evaluated by a newly developed analysis tool for visual evaluation. The simulation results such as burning behavior, temperature changes, and the burned away phenomenon of the door showed good agreement with those experimental results. Burning behavior in the kitchen, that couldn't be observed in the combustion experiment were grasped in detail in the simulation. Furthermore, the relationship between the fire source and the fire damage on the floor, which couldn't be explained only by the observation results after extinguishing the fire, could be reasonably explained by the visual evaluation of burning behavior and the accumulated heat-flux in the kitchen by using the simulation. Therefore, the fire simulation was shown to be an effective tool for analyzing fire phenomena.
