Abstract

Two new series of medium-scale tests were carried out, i.e., LNG vapor clouds produced with deliberately high gas concentrations to study fireball formation, and horizontal momentum releases of LPG, in which ignitability effects were presented. Extensive data were collected in both sets of experiments on vapor concentrations, flame development, and thermal radiation. Very different fires resulted from a jet release and from a high volume flux area release due to the concentration field in the two gas clouds. In the jet release, there was strong mixing with the ambient air and the concentrations were relatively small, compared with the deliberately vapor-rich area release where mixing is reduced and a significant fraction of the plume is above the upper flammability limit. In the jet release, the fire burned back from the ignition point to the source, and produced relatively little change in the jet.
