Sound Field Simulation and Optimization at an Underground Subway Station

Building Acoustics, 2013
The noise of underground subway stations has a great influence on the passengers and workers. The finite-element based software Actran is introduced to analyze the acoustical performance of an underground subway station in this paper. A sample station named Xingzhong Road from metro line 9 in Shanghai is considered.

Analysis of Spot Cooling in an Underground Subway Station

International Journal of Ventilation, 2004
AbstractRailway platform spot cooling has become an increasingly attractive means to improve thermal comfort conditions of existing subway stations. This paper presents a systematic approach to evaluate the effectiveness of platform spot cooling. The subway environment is first analysed by a simple one-dimensional network model, which is able to ...

Experimental and Numerical Investigation of Bypass Tunnel on Piston Effect of Underground Subway Station

open access: yesProceedings of the 6th International Conference on Informatics, Environment, Energy and Applications, 2017
With the rapid growth of the infrastructure constructions in China, more and more metro lines have been built in recent years. The piston wind have a significant influence on the air temperature and the flow field of subway stations and tunnels. The bypass wind tunnel located on both side of the platform, which have great effect of shunt piston wind ...

Transient variation of aerosol size distribution in an underground subway station

Environmental Monitoring and Assessment, 2016
As the number of people using rapid transit systems (subways) continues to rise in major cities worldwide, increasing attention has been given to the indoor air quality of underground stations. This study intended to observe the change of PM distribution by size in an underground station with PSDs installed located near the main road in downtown Seoul,
