Numerical Simulation of NOx and Particular Matter Distribution from Urban Street in Beijing China
Mechanical Engineering Department, Purdue University Calumet, 46323, Hammond, IN, US
In recent years, air quality has been a nation-wide issue in Beijing, China with frequent appearance of haze. Disappointingly, most detectors and sensors are mounted in suburb regions that are over ten kilometers away from the center of Beijing. Additionally, most researches are focusing on a general air flow in large scale instead of a specific community. It is important to be aware of the air quality at living communities in urban areas due to a large population. In this study, computational fluid dynamic (CFD) technologies were used to analyze the distribution of NOx and particular matter (PM) from urban street in Beijing to evaluate the air quality at a certain building. As most air pollutions are caused by vehicle emissions in urban areas, containing NOx and particular matters, traffic emissions were considered as the only source of contaminants in this study. Commercial software ANSYS Fluent® was used to simulate a number of dispersion scenarios under different boundary conditions to quantify the pollution level for the selected living environment in Beijing, China. Mass fraction, isosurfaces and streamlines of contaminant were presented to analyze the pollution distribution around the area
