Fire Engulfment of Pressure-Liquefied Gas Tanks: Experiments and Modeling

Source

The in-vessel transient thermohydraulics, under emergency relief, of tanks of heated pressure liquefied gases, determines whether vessels will safely relieve their contents, rupture and cause a pool or flashing jet fire, or catastrophically fail and boiling liquid expanding vapor explosions (BLEVE) resulting in a significant fire ball and rocketing debris.

This paper reviews the basic thermohydraulic phenomena and their interaction. The mech- anisms are illustrated with reference to direct visual observation in small vessels and the interpretation of additional data obtained in intermediate scale experiments.

The paper additionally describes a two-dimensional zone and a computational fluid dynamics (CFD) field technique to describe the tank and fluid behavior under fire attack conditions.
