Abstract;In this paper a series of study on the development of the urban fire simulation model using Fire Wind Tunnel experiments and CFD (Computational Fire Dynamics) results is presented. First, the existing simulation model was verified by comparing its results of the urban fires followed by the 1995 Kobe earthquake with the investigation conducted by the Tokyo Fire Department. Next, the existing urban fire simulation model was modified, namely, change of wind direction and wind speed was applied to the model on the basis of CFD results. Then, spot fires by fire brands were also applied to the model referring to the CFD results and so on. Finally, experimental study on a compartment fire affected by external wind was conducted using Fire Wind Facility in BRI. (author abst.)
