  • 摘要:

    根据数字全息干涉度量原理搭建了气液质扩散系数测量实验平台,设计并加工了中空不锈钢恒温扩散槽,采用自编程序进行数字图像处理,通过测量298.15 K时0.33 mol/L KCl溶液在水中的质扩散系数验证了实验系统的正确性。实验测量了常压下278.15~343.15 K温度范围内CO2在RP5航空燃油中的质扩散系数。随着温度的增加,CO2在RP5航空燃油中的质扩散系数逐渐增大。不同温度下的质扩散系数可利用Arrhenius方程模型进行拟合,而且质扩散系数理论模型计算与实验测量结果之间的相对误差均小于9.51%。在实际工程应用中,可根据拟合的Arrhenius方程对CO2在RP5航空燃油中的质扩散系数进行准确的预测,实验测量结果为燃油箱惰化系统的优化设计提供了数据支持。
