Indoor Air Quality And The Flow Field Relations

This paper analyses the significance of the study of indoor air quality, summaries the development of the research on indoor air quality, and narrates the advantage of appliance of computational fluid dynamics on IAQ research.Then the paper dissertates the method applying some guidelines, such as efficiency, to evaluate the indoor air distribution.By the numerical simulation, calculate the distribution of velocity^ temperature and contaminant concentration of air in the room under different modes of air flow organization, and through analysing the outcomes of simulation, draw some conclusions.
