Numerical simulation analysis of platform screen door systems

By means of combined one dimensional and three dimensional numerical simulation methods, analyses the air distribution and temperature field and checks the ventilation rate of the screen door system with controllable vents. The results show that the air velocity and temperature are acceptable for the passengers and the air changes can meet the requirement of underground railway specification; and that this energy saving platform screen door system can meet the comfort requirements of the passengers and has better effects in reducing energy consumption in transitional seasons, providing a reference for the environmental control design of underground railway stations.
