摘要
为研究低温输送系统的低温垂直管路中可能出现的间歇泉现象,采用液氮为工质,进行了间歇泉现象模拟实验研究.实验纪录了不同的管路结构及不同绝热结构条件下,管路出现的振动信号及管路温度分布,并将实验结果与Murphy曲线进行了对比.结果表明,管路的长径比和绝热结构对间歇泉现象的产生有较大的影响.
A geyering experiment study in vertical cryogenic transfer system was made with liquid nitrogen as a working fluid. The vibration and temperature distribution ware recorded in different pipe structure and insulation conditions. The results of experiment were compared with the Murphy's result. From the results, it is clear that geysering is significantly affected by the pipe's structure and insulation conditions.
