摘要/Abstract

摘要： 飞机停靠廊桥时,客舱内空气质量的优劣直接影响机组成员的工作效率。为分析桥载空调送风速度对客舱内部空气质量的影响。将波音737飞机头等舱作为研究对象,以CFD方法和传热学为基础,对飞机客舱内空气质量进行数值模拟。利用P_MV与CO₂相对浓度为基础的新指标(I_AO)作为客舱内空气质量的评价标准,通过Gaussian法拟合曲线,得出评价指标I_AO与送风速度的函数关系,分析结果表明,送风速度过大或过小对客舱内空气质量有较大影响,送风速度为0.82m/s附近时,空气质量最佳,最后通过拟合优度检验与实际调查,证实了其可靠度与可行性,可以作为桥载空调控制的参考依据。

Abstract: The air quality in the cabin will directly affect the persons’ efficiency when an aircraft berths. In order to analyze the effect of velocity of air outlet of bridge-load air conditioning on the air quality of aircraft cabin, the first class cabin of Boeing 737 aircraft is used as the research object, based on the CFD method and numerical heat transfer theory, the air quality in aircraft cabin is simulated numerically. Based on P_MV and CO₂ relative concentration, a new air quality index (I_AO) is put forward to evaluate the air quality of aircraft cabin, and then it make the new index (I_AO) as function of the velocity of air supple outlet through the Gaussian fitting curve method. The results show that supply air velocity has great effects on air quality of aircraft cabin no matter it is oversize or undersize. When the supply air velocity is about 0.82m/s, the air quality of aircraft cabin is the best. The reliability and effectiveness is proved by goodness-of-fit tests and actual investigate, so the speed can provide the basis for bridge-load air conditioning control.

Key words: aircraft cabin, CFD method, curve fitting, air quality, goodness-of-fit tests
