无损贮存及涨罐饱和相热力学模型研究

Saturation phase thermodynamics model research of no-loss storage and rising tank

在低温液体无损贮存及涨罐研究方面,经常采用一种假设容器内气、液相均为饱和相的热力学模型。这种模型比较符合实际,并能够大大简化容器内的热力学状态,是一种比较常用的热力学模型。文中利用一个5m3低温贮罐进行的液氮无损贮存及涨罐试验,对该热力学模型进行了对比研究,讨论了饱和相热力学模型误差产生的原因,对于无损贮存和涨罐研究具有指导意义。

In the research of no - loss storage of cryogenic fluid and rising tank, the thermodynamics model was usually adopted to assume that the gas and fluid phases were saturated. The model agreed with the fact well and greatly simplify the thermodynamics state of the tank, so it is commonly used. In this paper, an experiment of no - loss storage and rising tank was conducted in a 5m^3 cryogenic tank. The model was comparably studied and the cause of error was discussed. The results are valuable for the research of no - loss storage and rising tank.
