摘要
民机客舱内部空间封闭狭小、人员密集,常会引发致病菌的扩散传播。致病菌在民机客舱内传播途径主要有直接接触传播、间接接触传播和空气传播。通过建立客舱空气的CFD数值仿真模型,探究了3种客舱供气方式下,致病菌在客舱空气中的传播规律和病菌分布浓度的影响因素。在塑料和织物里面通过添加各种抑菌材料,实现了客舱内设施表面抑菌功能改性。对这些研究成果和研究现状进行综述总结,同时指出应进一步结合民机客舱低压、低湿度的特殊环境开展工程应用实践研究,以及高预测精度的CFD模型理论研究。
The internal space of civil aircraft cabin is narrow and crowded,it often causes the spread of pathogenic bacteria.The main transmission ways of pathogenic bacteria in the cabin of civil aircraft include direct contact transmission,indirect contact transmission and air transmission.In order to prevent the transmission of pathogenic bacteria of indirect contact and air contact,experts at home and abroad have achieved double effects of filtering and bacteriostasis by the fix of bacteriostatic agents on HEPA filter or the research and development of filter materials with bacteriostasis function.The experts have the exploration of the dissemination rule of pathogenic bacteria in cabin air and the influencing factors of bacterial distribution concentration under three kinds ways,through the establishment of CFD numerical simulation model of cabin air.And they did the surface bacteriostatic function of facilities in cabin was modified,by adding various bacteriostatic materials in plastics and fabrics.These research results and research status were summarized,and pointed out that engineering application practice research should be further carried out in combination with the special environment of low pressure and low humidity in the cabin of civil aircraft,as well as the theoretical research of CFD model with high prediction accuracy.
