【摘要】：建立了大型LNG储罐分层及翻滚模型,充分考虑了LNG多组分、变物性的特点,分别研究了分层破坏的机理及分层温差、分层高度、漏热量和漏热位置对翻滚剧烈程度的影响。结果表明:当底部漏热为10 W/m~2,上下层温差大于0.2 K时会发生翻滚,且温差越大,翻滚发生越容易,翻滚程度越剧烈。当底部漏热10 W/m~2,上下层高度越接近时,翻滚程度越剧烈。无论是底部漏热还是侧壁漏热,漏热量越大时,翻滚程度越剧烈。漏热量相同时,侧壁漏热发生翻滚的时间要早于底部漏热,但剧烈程度要小于底部漏热。
[Abstract]:The delamination and rolling model of large LNG storage tank is established, and the characteristics of multi-component and variable physical properties of LNG are fully considered. the mechanism of delamination failure and the effects of delamination temperature difference, delamination height, heat leakage and heat leakage position on the intensity of rolling are studied respectively. The results show that when the bottom heat leakage is 10 W 鈮，
