Abstract
Even though BLEVEs have been studied by a number of
authors, there are still significant gaps in their
knowledge and in the prediction of their physical
effects. Diverse methodologies have been proposed to
calculate the peak overpressure of
the explosion, but their results sh
ow an important scattering. Most of
them assume a reversible, isentropic phenomenon, not at
all logical for an explosion. Instead, some recent
papers have assumed an irreversible process, much
closer to the real phenomenon. This communication
analyses these aspects, comparing the results obtaine
d by applying the diverse methodologies to data
obtained from a real case. The uncertainties found (v
essel failure mode, directional effects) are also
commented. Finally, some conclusions are derived on the best way to estimate the overpressure.
