Abstract
A physics-based urban fire spread model formerly developed by the authors was refined by considering fire fighting activities of community residents. The model is based upon the zone concept in which properties of gas inside compartment, component of buildings in urban area, is assumed as uniform. Mitigation of fire hazard due to water application is evaluated by incorporating following consequences of water evaporation into the conservation equations of compartment gas : (A) cooling of compartment gas ; (B) dilution of compartment gas ; (C) cooling and wetting of fuel surface. Initiation time of water application, which is a predominant factor of success and failure of fire suppression, is evaluated as a sum of detection time of fire , assembling time of residents, and preparation time for equipment use. The proposed model was applied to simulate fire spread behaviors in a hypothetical urban area where 121 buildings of identical configuration were aligned in a regular pattern. Case studies were carried out in order to investigate effects of anticipated critical parameters such as fire detection time, and number of water supply port.
