| 摘 要： | 研究液化天然气(LNG)低温大型SPB型储液罐在海上运动过程中晃动引起的对液舱壁面产生的动侧压力、储液的气液混合情况、储液的晃动幅度及液舱内压力分布。基于VOF(volume-of-fluid)模型模拟二维SPB型液舱内储液的晃动特性,并利用试验数据对模型的计算结果进行了验证。结果表明:模拟数据与试验数据吻合较好;晃动幅度与运输船的初始速度有关,初始速度越大,晃动就越剧烈;不同储液充满率引起的晃动不同,充满率越大,晃动的幅度越小,有利于减小储液的晃动;在液舱内合理的设置阻流板有利于抑制晃动。

| Abstract: | The side pressure caused by the liquid sloshing,the gas-liquid mixing situation,the liquid sloshing amplitude and the pressure distribution in containers were studied in liquefied natural gas(LNG) cryogenic large SPB-type storage tanks.The liquid sloshing characteristics in two-dimensional membrane SPB-type tank were simulated based on VOF(volume-of-fluid) model.The simulated results were compared with the experimental data.The results show that the simulation data agree well with the experimental data.The ... |
