摘要：

为了更好地预测和模拟低温液体无损储存过程，保障储存、运输安全，建立数学物理模型去仿真无损储存过程是必要的。在已有的俄罗斯无损储存模型的基础上，对计算过程中的漏热量用实时的低温液体温度进行修正。将修正前后的俄罗斯模型应用在2 m³液氮无损储存实验上，并将实验升压数据与计算结果进行比较，验证了修正模型对降低原俄罗斯半经验模型偏差的有效性。结果显示，修正前后的俄罗斯模型产生的误差都是同向负偏差，漏热量经过修正后，负偏差减小。同时将修正后的经验公式的计算结果和更复杂的分层模型的计算结果进行比较，指出复杂度的提升并没有带来精度的提高，修正后的俄罗斯模型适用于工程应用。

Abstract:

Mathematical and physical model should be established to simulate and predict the process of ventless storage to guarantee the safety of storage and transportation. Based on semi-empirical model established by Russian scholars, heat leak was revised in this paper to better simulate the ventless storage process. The revised model was applied on a 2 m³ liquid nitrogen ventless storage experiment. The results of calculation and experiment were compared to validate the effectiveness of the heat leak revision. The result showed that the errors of the Russian model and the revised model were both negative. The absolute value of error was reduced after revision. Same working condition was also calculated with thermal stratification model of higher complexity. However, the revised Russian model still showed better performance in predicting this ventless storage process and was much easier to use in engineering situations.
