摘要
Based on the analysis of the whole process of LNG spill on land,the research methods of LNG pool expansion and heavy gas diffusion are summarized and analyzed.This paper reviews the experimental and analytical work performed to data on spill of LNG.Specifically,experiments on the spill of LNG onshore,as well as experiments and numerical study on heavy gas dispersion.Pool boiling and turbulence model are described and discussed,as well as models used to predict dispersion.Although there have been significant progress in understanding the behavior of LNG spills,technical knowledge gaps to improve hazard prediction are still identified.Some of the gaps can be addressed with current modeling and testing capabilities.Finally,a discussion of the state of knowledge,and recommendations to further improvement the understanding of the behavior of LNG spills onshore.
