液氧贮箱增压过程中气枕空间温度场的数值模拟

摘要

Heat and mass transfer model based on the two film resistance theory were built by simulating non-steady heat flow process within the tank, the ullage temperature variation and its influence on low temperature liquid oxygen in pressurization gas transport process was analyzed.%液氧贮箱增压气体输送过程中,气枕空间的温度场会发生较大的变化,并且会引起相界面附近低温液体的温升.基于双膜阻理论建立热质交换模型,通过模拟贮箱内非稳态热流过程,分析气枕空间在增压气体输送过程中温度场的变化及其对于贮箱内低温液氧的影响.
