摘要
四氧化二氮在低温条件下容易凝结为固体而对航天发射产生难以预见的影响,本文依据非稳态传热理论对低温环境中不同管径圆柱管道内的四氧化二氮导热情况进行了研究,建立了圆柱管道四氧化二氮低温非稳态导热模型,经验证与实际情况拟合较好。
Liquid dinitrogen tetroxide (N2O4) tends to change to solid phase in low temperature which may affect the launch progress. Based on the theory of transient heat conduction, the transient heat conduction of N2O4 in pipes of different diameters was researched, and the transient heat conduction model of N2O4 in low temperature was established. Tests show that the experimental and the model results are in good accordance.
