摘要: 为充分认识飞机座舱内污染物传播机理并控制和减少座舱内污染物传播,研究了不同送风方式对座舱内污染物传播特性及空气品质的影响。以波音737-200机型为研究对象,利用CFD技术建立了5排座舱模型,模拟计算了天花板和天花板+侧壁两种送风方式下座舱内气流场及污染物浓度场,通过等比例实验舱对部分工况气流场和污染物浓度值进行验证,并以空气龄为评价指标对空气品质进行评价。结果表明:在同等送风量下,天花板+侧壁送风更有利于污染物的扩散,通风效果充分,而天花板送风更容易造成污染物单点聚积,通风效果较差,且经济性较差。

Abstract: To understand contaminant transmission mechanism well and control and reduce the contaminant within the aircraft cabin, the influence of different air supply modes on the contaminant transmission characteristics and air quality within the aircraft cabin is investigated. A five-row cabin model for a Boeing 737-200 is established by the CFD technology, and the airflow field and contaminant concentration field within the cabin are calculated when two air supply modes are adopted:air supply via ceiling, and air supply via ceiling and wall sides. Experiments are performed in the cabin mockup to validate the calculation results. The air quality is evaluated by air age, which is used as an evaluation index. The results indicate that the air supply mode via ceiling and wall sides is more conductive to contaminant transmission, and the ventilation is more sufficient; while the air supply mode via ceiling is more likely to cause a high contaminant concentration around the contaminant source, the ventilation is poor, and the cost is high.
