LNG船舶瞬时泄漏扩散状态的建模与仿真

Modeling and simulation analysis of transient leakage and diffusion of LNG ship

随着可持续发展观的普及,能源结构中液化天然气的比重逐渐超过了煤炭和石油,成为工业和生活的主要能源。液化天然气需求的剧增对其运输和存储提出了新的要求,作为海上液化天然气运输的主要途径,LNG船舶的研究和开发引起了国际上的广泛关注。本文分析LNG船的瞬时泄漏原因和扩散过程,应用数学模型对瞬时泄漏和扩散过程进行建模与仿真分析。

With the popularization of the concept of sustainable development, the proportion of liquefied natural gas in the energy structure has gradually exceeded the coal and oil. Liquefied natural gas demand growth has put forward new requirements for the transport and storage conditions, as the main way of offshore LNG transportation, research and development of LNG ship has aroused widespread concern internationally. In this paper, the cause and process of the instantaneous leakage of LNG are analyzed in detail. The mathematical model is used to simulate and analyze the transient leakage.
