液氢长距离管道输送探讨

Discussion on long distance pipe transfer of liquid hydrogen

讨论了液氢在长距离管道输送中存在着最佳流速,并分析了实际液氢输送过程中的输送状态。对在稳定的大流量转注过程中存在的单相流和两相流两种流动状态分别给出了在不同压力、流速、漏热等情况下温升、蒸气含量的理论计算结果,并在试验的结果上对液氢的流动状态给出了一些看法。

The optimal flow rate existence in the long distance pipe transfer of liquid hydrogen was demonstrated. The status of liquid hydrogen during practical transfer course was analyzed. The theoretical analysis of temperature rising and steam content under different pressures, flow rates, heat leaks, etc are displayed for single-phase and double-phase flow states during steady, fast transfer process. Furthermore, some opinions about the flow status based on experimental results are presented.
