The Computer Simulation and Verification Analysis of Fire Scene

Abstract

It is the most direct way to study fire cases through the actual fire. Therefore, if the process of fire can be reconstructed and quantified, we can not only more realize the actual action of the fire but also enhance the practicability of fire prevention. The research discusses an actual fire event of a residence in Chiayi County, Taiwan. The case was an arson attack with gasoline, and it caused the tragedy of 3 deaths and 1 severe injury. This research applies FDS (Fire Dynamics Simulator) developed from NIST to numerical simulation of the fire, makes proper assumptions under the fire description and program limitations, uses qualitative and quantitative methods for restoring and verifying the fire scene, and discusses the distribution of the temperature. Analytical result of this research could be served as the references for fire prevention engineering.
