| 摘要随着社会经济的发展以及人们对便捷交通的需求，人们对客车室内的环境舒适度的要求也在逐渐增加。客车室内空气品质，不仅对驾乘人员的舒适度有直接关系，而且也会直接影响驾乘人员的健康。由于客车在运行过程中不可避免地产生一些有害气体，同时空调客车的厢体为密封结构，并且空调只能改变车厢内的温度和湿度。 鉴于此，本文以一款客车专用并且能够进行有害气体净化的智能环保天窗为研究对象，以计算流体力学为基础，借助FLUENT 流体分析软件对客车室内的污染物净化问题进行模拟，对车室内空气污染物进行多组分分析，得出车室内空气的净化情况。21968 本文首先介绍本课题的研究背景和意义，并简要叙述了国内外的研究现状，其次介绍了湍流理论、湍流模型以及FLUENT 流体分析软件。然后利用FLUENT 软件对客车室内流场进行建模和求解设置，对车室内空气污染物进行多组分分析，最后以模拟计算的结果为基础，对客车内部的空气污染物进行净化分析。 关键词 智能天窗 FLUENT 客车 空气污染 净化 毕业论文设计说明书（论文）外文摘要 Title The purification and analysis of environmental protection intelligent skylight bus interior gas pollution Abstract With the development of the social economy and the demand for convenient transportation, For passenger comfort requirements of car indoor environment is also increasing. Bus indoor air quality, not only has a direct impact on passenger’s comfort, but also about the health of passengers. Bus inevitably produces some harmful gas in the operation of the bus. Meanwhile, air-conditioned bus’s structure is box structure, and the bus only changes the temperature and humidity. In view of this, in this paper, a dedicated bus about harmful gas purification intelligent skylights can be for the study, based on computational fluid dynamics, with FLUENT fluid analysis software for bus indoor pollutants purification problems simulate, and multi-component analysis is carried out on the car indoor air pollutants, coming to purify indoor air condition. This paper introduces the research background and significance of the subject, and briefly describes the research status at home and abroad, secondly, it introduces the theory of turbulence, turbulence model and FLUENT fluid analysis software. Then we use FLUENT software to do modeling and solving Settings of the bus interior flow field , and do multi-component analysis for indoor air pollutants, finally, based on the results of simulation, to purify and analyze the air pollutants inside the bus.
