Numerical analysis of fire consequences and effective solutions in a corn starch explosion fire based on computational fire dynamics simulator

The trend of large-scale parties is gradually increasing. It is necessary to pay attention to the safety of personnel participating in activities and to study the impact of evacuation methods and safety on the fire caused by the explosion of large-scale parties. Fire accident investigation has found that most of the casualties and personnel can not immediately evacuated, resulting in smoke suffocation, high temperature burns and stampede. In this study, according to the structure of the actual venue and the distribution of personnel, we can use the computer to reconstruction of the fire site for assessment and analysis. This study uses fire dynamics simulator (FDS) + EVAC software to address the issue of Formosa Fun Coast explosion in Taiwan in several ways. FDS is a computational fluid dynamics (CFD) model developed specifically for fire driven flows, FDS is routinely applied to a wide range of problems including performance-based design, fire reconstructions, and test planning. Based on the advantages of CFD, the characteristics of explosion fire were studied; the specific and effective methods were put forward to reduce the casualties. There are many ways to improve the fire situation, we use ventilation system and sprinkler system device is a fast and effective program, the simulation is a good design. And this paper points out some problems that people should pay attention to in the actual fire process. It has certain guiding significance to the personnel; it can also reduce the harm degree of all the personnel in the activity, and enhance the safety of the large-scale activity.
