The environment of the aircraft cabin greatly influences the comfort and health of passengers and crew members. Contaminant transport has a strong effect on disease spreading in the cabin environment. To obtain the complex cabin contaminant distribution fields accurately and completely, which is also essential to provide solid and precise data for computational fluid dynamics (CFD) model validation, this paper aimed to investigate and improve the method for simultaneous particle and gaseous contaminant fields measurement. The experiment was conducted in a functional MD-82 aircraft. Sulfur hexafluoride (SF) was used as tracer gas, and Di-Ethyl-Hexyl-Sebacat (DEHS) was used as particulate contaminant. The whole measurement was completed in a part of the economy-class cabin without heating manikins or occupied with heating manikins. The experimental method, in terms of pollutant source setting, sampling points and schedule, was investigated. Statistical analysis showed that appropriately modified sampling grid was able to provide reasonable data. A small difference in the source locations can lead to a significant difference in cabin contaminant fields. And the relationship between gaseous and particulate pollutant transport was also discussed through tracking behavior analysis.
飞机机舱环境对乘客和机组人员的舒适度及健康有很大影响。污染物传输对机舱环境中的疾病传播有强烈影响。为了准确、全面地获取复杂的机舱污染物分布场，这对于为计算流体动力学（CFD）模型验证提供可靠、精确的数据也至关重要，本文旨在研究并改进同时测量颗粒污染物和气态污染物场的方法。实验在一架功能正常的MD - 82飞机上进行。六氟化硫（SF）用作示踪气体，癸二酸二（2 - 乙基己基）酯（DEHS）用作颗粒污染物。整个测量在经济舱的一部分区域完成，该区域要么没有加热人体模型，要么放置了加热人体模型。对实验方法在污染物源设置、采样点和采样计划方面进行了研究。统计分析表明，适当修改后的采样网格能够提供合理的数据。源位置的微小差异可能导致机舱污染物场的显著差异。并且还通过追踪行为分析讨论了气态和颗粒污染物传输之间的关系。
