The Numerical Prediction and Safety Analysis of Alternative Fuels Leakage Accident during Storage and Transportation

Using alternative fuels is an effective way to reduce air pollution and transform energy structure. The characteristics of four kinds vehicle alternative fuels (LPG, DME, CNG and hydrogen), and the advantages and disadvantages in practical application are studied in this paper. By using the methods which combines safety system engineering and Computational Fluid Dynamics (CFD), the diffusion process of fuels leakage, and the damage area were analyzed quantitatively. Moreover, potential fire accidents for alternative fuels during storage and transportation were evaluated by consequence assessment method. The study results show damage area of the fireball's radiation, which provides reference for fuel safety analysis.
