The purpose of this study is to develop a real time prediction method for a large-scale urban fire. Such large-scale urban fire is well known as the secondary disaster which follows a devastating earthquake. The real time prediction of fire can help smooth evacuation of residents from dangerous parts of a disaster area. In this study, CFD method is applied to simulate fire plume and its surrounding wind field. Great earthquakes are often followed by large-scale urban fire disasters. The famous examples are the Kanto Earthquake(Tokyo:1923) and the Hanshin-Awaji Earthquake (Kobe:1995) in Japan. From the viewpoint of social safety control, it is quite important to develop a predicting and planning method to minimize the secondary disaster. The method should be equipped with the properties of real time simulation. So it can predict fire phenomena in real time manner to support residents for evacuating and to help fire fighters for extinguishing conflagration. In this study, 3D CFD analysis of wind and temperature fields over Kobe city which experienced a large-scale fire just after the Hanshin-Awaji (Kobe) Earthquake is implemented with the aid of a meso-scale climate model. The field data measured on the date, when earthquake occurred, are used for the boundary and initial conditions of this study to simulate the large-scale fire plume over Kobe city. This numerical analysis deals with the large-scale wind field. The effects of strong heat radiation, fire bands on combustion, and fire spreading are not considered for the study. In the simulation, the thermal plume and the surrounding wind converging to the center of fire are predicted. In the future, the fire bands and radiation models will be investigated to develop a fire simulation code.
