摘要

摘要: 以B737NG客舱模型为对象, 采用CFD方法在无乘客的工况下分析了天花板送风、行李架送风、天花板和行李架送风、天花板和个人送风口送风等4种送风方式下飞机座舱气流速度、温度、甲醛浓度和二氧化碳浓度的分布情况。研究结果表明: 第3、4种送风方式下座舱内的气流速度分布较均匀, 乘客座位附近的气流速度约为0.2 m·s^-1; 第4种送风方式下座舱内的温度分布最均匀, 温度从送风口到乘客座位附近逐渐上升到296K;第3、4种送风方式下座舱内的甲醛浓度较低; 4种送风方式下座舱内的二氧化碳浓度均在标准范围内, 可见, 采用天花板和个人送风口送风方式能使座舱气流速度和温度分布更均匀, 空气污染物去除效果更好, 能够得到更好的空气质量。

Abstract: B737NG cabin model was taken as object, and CFD method was used under the working condition of no passenger to analyze the distributions of air velocity, temperature, formaldehyde concentration and carbon dioxide concentration in aircraft cabin under four kinds of air supply modes, named ceiling air supply mode, luggage rack air supply mode, ceiling and luggage rack air supply mode, and ceiling and personal air supply port air supply mode.Research result shows that under the third and fourth air supply modes, the distributions of air velocity in cabin are uniform, and air velocity near to passenger seat is about 0.2 m·s^-1.Under the fourth air supply mode, the distribution of temperature in cabin is most uniform, and the temperature increases gradually to 296 K from air supply port to passenger seat.Under the third and fourth air supply modes, the formaldehyde concentration in cabin is lower.Under four air supply modes, the carbon dioxide concentration in cabin is in the standard range.Among four kinds of air supply modes, ceiling and personal air supply port air supply mode can make the distributions of air velocity and temperature more uniform, remove air pollutants more effectively, and provide better air quality.
