Many cQmputationai伽id dynamics(CFD)models have been presented fQr gas dispersion prediction but few models have been applied to gas dispersion re$ulted from lique且ed natural gas(LNG)evapora・tion、This report compares the calculations of CFD model‘‘SIGMET-J”with many reliable data of LNG 丘eld tests alld con丘rms the validity of this model.
