Boiling liquid expanding vapour explosions (BLEVE) in CO2 vessels: initial experiments.

Author(s) : PETTERSEN J., HAKENJOS J.

Summary

A BLEVE may occur when a vessel containing pressurised liquid or supercritical fluid is rapidly depressurised, e.g. due to a crack or a rupture. The sudden depressurisation leads to instant vaporization that may give a transient overpressure peak. In some cases the overpressure can be high enough to rupture the whole vessel, with a resulting blast wave and risk of flying fragments. An experimental study at NTNU/SINTEF aims at improving the understanding of BLEVE in CO2 systems. Tests results are reported.
