Assessment Method of Liquid Fuel Field Explosion Hazardousness

Studying the parameters of fuel explosion fireball is an important measure for hazardousness assessment. In this paper, traditional methods are summarized and a new method of fireball characterization by which the heat released from detonation agent and liquid fuel could be distinguished is presented. In this method, the explosion processes, explosion properties and explosion damage are studied by capturing the high speed images and thermal images of explosion fireball. Among them, the analysis of explosion properties is the most important part, including fireball size, spreading rate of fireball diameter, surface temperature and radiation intensity of fireball. The hazardousness of liquid fuel field explosion could be evaluated through both single-parameter and multi-parameters combined in this method. Four examples are selected to indicate the effectiveness of this method.
