摘要
应用仲氢转化制冷技术,针对液氢无损储存过程,建立液氢储罐中仲氢转化的物理模型,进行液氢储存的流场温度场仿真,研究仲氢转化对液氢储存的影响。分析结果表明,储罐内的液氢经过仲氢转化器后,温度降低,密度增大,有助于罐内液氢自然对流循环的完成。
The physical model of parahydrogen conversion in the no-vent liquid hydrogen storage vessel was founded,using the technology of parahydrogen refrigeration. The flow field and temperature field were simulated,and the effect of parahydrogen conversion on liquid hydrogen storage was researched. The result indicates that after passing through the parahydrogen conversion container,the temperature of the liquid hydrogen in the vessel decrease, and the density increase. This trend is helpful to the free convection process of liquid hydrogen.
