Abstract

This is a study on environment inside subway cabin under the effects of piston winds. Subway trains move fast in underground tunnels and induce strong piston winds which will change the atmospheric environment around every cabin. Through a more realistic Computational Fluid Dynamics approach with a full-scale geometry model of tunnel and a subway train made up by four cabins. This paper got conclusions about the spatial distribution of velocity, pressure and temperature in cabins which are helpful to optimize the Environment Control Systems (ECS) in every single cabin and improve the comfort level for commuters.
