Study on LNG leakage and diffusion in dangerous goods logistics park

Abstract

In this paper, according to the idea of "forward model algorithm of leakage and diffusion", the research on LNG leakage and diffusion in dangerous goods logistics park is completed, the main research contents are as follows: 1) An improved forward Gaussian diffusion model of LNG is established to modify the parameters according to the specific environment of dangerous goods logistics park. 2) The safety trace software is used to simulate the process of LNG leakage and diffusion in the hazardous materials logistics park. The applicability of the improved Gaussian diffusion model in the case of LNG tank leakage in the dangerous goods logistics park is verified by the influence of the downwind distance of the concentration contour line and environmental factors on the leakage and diffusion.
