Numerical Simulation of the Concentration of Pollutants in Underground Parking Garage

Gu Dengfeng, Zhang Ling and Zhou Chunhui (School of Civil Engineering, Hunan University)  
Based on the practical surveys of the ventilation system in underground parking garage and accorded to the particular air environment of the garage, the air distribution is numerically simulated by software Fluent. The simulated data nearly inosculate with the practical surveys. Furthermore, CO concentration field is simulated. The average concentration of the pollutants which is simulated by computational fluid dynamics is also congruous with the practical data, and it indicates the method is correct. A simple and visualized method is supplied for predicting the average concentration of the pollutants and in underground parking garage and controlling the ventilation system at real time.
