摘要
The explosion of a road tanker transporting LNG (one person killed, two injured) is studied. The analysis shows that the explosion. which followed a two-step mode as for the failure of the vessel, could have been a boiling liquid expanding vapor explosion (BLEVE). The overpressure and thermal radiation have been estimated and related to the effects observed. Only a relatively small part of the energy released in the explosion was manifested in the pressure wave. The large fragments (the three pieces into which the tank was broken) and the truck motor were ejected at various distances along the tank's main axis. (C) 2004 Elsevier Ltd. All rights reserved.
