一种描述燃油与气体组分传质的频率传质模型

Frequency mass transfer model describeing mass transfer between fuel and air

  • 摘要: 抛开经典Fick定律,提出用传质频率来表征燃油和空气氧氮传质的快慢,建立了以频率传质模型为基础的飞机燃油箱冲洗惰化数学模型,该模型能对传质速度进行量化,而国内外工程界目前使用的模型不具备此量化能力;该数学模型的准确性和有效性得到美国联邦航空管理局(FAA)相关封闭燃油箱内的氧氮传质实验数据的验证;将该数学模型用于仿真A320的飞行阶段的氧的体积分数,仿真结果同测试数据及其他模型的计算结果对比后发现:频率传质模型的计算精度最高;进一步仿真表明,载油率的增加会明显延缓惰化氧的体积分数的降低,且在高载油率下频率传质模型同不传质以及瞬时平衡这两种模型的计算结果差异很大.
