On the flash fire of stratified cloud of liquefied natural gas

This work was focused on the characterization of flash fire scenarios resulting from the accidental release of liquefied natural gas (LNG) by keeping into account vapour stratification and temperature gradient, which deeply modify the combustion phenomena for the standard homogeneous cloud. An open-source computational fluid dynamic (CFD) tool was used to this aim, provided premixed and diffusive/convective modification for the combustion model.
