Abstract
The Boiling liquid expanding vapor explosion (BLEVE) refers to a catastrophic explosion that occurs when a vessel containing a pressure liquified gas at a temperature well above its atmospheric boiling point experiences total loss of containment. The vessel completely opens and hazards are produced posing risks to nearby populated areas and critical infrastructure. Studying partial failures aids in developing strategies to minimize potential damage from associated hazards such as ground load, projectiles, and near-field overpressure. Understanding the characteristics of partial failure mechanism provides valuable insights for identifying factors influencing vessel opening and increasing the severity of BLEVE incidents. New small-scale propane 2022 BLEVE experiments on 589 cm3 aluminium vessels were conducted at IMT mines Ales, France, for different operating conditions. Through a sensitivity analysis, this study investigates the factors contributing to partial failure, and how the type of opening contributes to a less or more powerful hazards.
