Effect of traffic-related pollutant on indoor air quality in buildings along main roads

摘要

A model combined CFD technology and the indoor multi-zone network model was presented in this paper to investigate the effect of traffic-related pollutant on indoor environment. This method considered both spatial distribution of wind pressure and pollutant at building surface. Using this model, the effect of wind speed and wind direction on the diffusion process of outdoor traffic-related pollutants into indoor environment is investigated. The simulation results show that large wind speed can reduce the effect of outdoor traffic-related pollutant. The building located at windward of the street has more effect by outdoor traffic-related pollutant than that located at leeward of the street.
