摘要
为模拟液化天然气(LNG)船舶水面泄漏产生液池的扩展过程,运用泄漏源强、液池蒸发和液池扩展模型,对液化天然气液池水面扩展过程进行数值分析.数值分析结果表明,液化天然气船舶不同裂口直径情况下,泄漏源强随裂口直径增加而增强,液池扩展范围随源强增强而扩大;不同大气平均风速情况下,液池扩展范围随风速的增强而缩小.
As an accident of LNG vessel which makes for penetrate holes in LNG cargo tank happening,LNG cargo releasing from holes shapes an unconfined pool on water.Aiming at this physics process,using 'release rate model' 'evaporation model' and 'pool spreading model' to simulate the spreading process of the unconfined pool releasing from LNG vessel cargo tank.① Base on consequence of numerical analysis,as the penetrate hole size increasing,the release rate and max pool size increasing.② Base on consequence of numerical analysis,as the wind speed increasing,the max size of pool spread on water decreasing.
