【摘要】：建立了大型LNG儲(chǔ)罐分層及翻滾模型,充分考慮了LNG多組分、變物性的特點(diǎn),分別研究了分層破壞的機(jī)理及分層溫差、分層高度、漏熱量和漏熱位置對(duì)翻滾劇烈程度的影響。結(jié)果表明:當(dāng)?shù)撞柯釣?0 W/m~2,上下層溫差大于0.2 K時(shí)會(huì)發(fā)生翻滾,且溫差越大,翻滾發(fā)生越容易,翻滾程度越劇烈。當(dāng)?shù)撞柯?0 W/m~2,上下層高度越接近時(shí),翻滾程度越劇烈。無(wú)論是底部漏熱還是側(cè)壁漏熱,漏熱量越大時(shí),翻滾程度越劇烈。漏熱量相同時(shí),側(cè)壁漏熱發(fā)生翻滾的時(shí)間要早于底部漏熱,但劇烈程度要小于底部漏熱。
[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，
