| Abstract: | In this paper, the dispersion models commonly used for LNG were firstly introduced, and then their advantage and disadvantages were analyzed, CFD model of LNG release and dispersion was focused, and CFD model validation data by many large LNG leakage tests was also analyzed. The results showed that the CFD dispersion model was more precise in predicting dispersion of methane than the others. |
