Computer simulation and analysis of automobile exhaust gas in elevated annular traffic lanes of Beijing South Railway Station

Simulates the air quality of different regions in the elevated annular traffic lanes in summer under extremely adverse environmental condition with the CFD software. Starting with requirements specified in the national standard GB 30951996 Ambient air quality standard and the ProPECC PN 1/98 Control of air pollution in semi-confined public transport interchanges, analyses the concentration distribution of contaminants and considers that the air quality of the elevated annular traffic lanes can basically satisfy the safety and health requirements. Based on the simulated result gives the set position of fresh air intakes.
