The role of numerical modeling in scientific fire investigation

Fire risk is perhaps the most common in category of special emergencies, being a phenomenon that affects important areas economic and social life, such as buildings, industrial facilities, public spaces, forests, crops, or transportation. Scientific investigation fires constituted set organized actions, technical nature, undertaken to determine causes led occurrence fires, source ignition, circumstances favored event. Numerical fire modeling widely recognized accepted tool for analysis research. The results carried out on-site are compared with evolution obtained by computer simulation, using numerical models based on known input data, verify different hypotheses regarding cause fire. advantages over experimental methods expressed low costs substantial time savings. Moreover, several simulations can be run simultaneously, scenarios event consequences. paper presents main FDS brings technical-scientific expertise fire, implications data analysis, development, testing hypotheses, respectively selection process final hypothesis. words.
