In order to avoid pneumoconiosis and other hazards caused by excessive concentrations of
dust in construction tunnels, this paper applies CFD numerical simulation, in combination …

In subway stations, the piston effect plays an important role in enhancing ventilation to
improve subway environment and reduce energy consumption. However, it may induce …

Piston action can affect the thermal environment inside the tunnel by changing the air
pressure and velocity. This is extremely unfavorable for tunnels in cold regions because it …

The metro is an indispensable transportation system in big cities and the primary commuting
method for city residents. Ventilation primarily controls metro environmental health. The …

Subway transportation systems are in rapid development and energy consumption in
subway stations is becoming more and more significant. The present paper aims to reveal …

In this study, the spatial distribution of the transient pressure and the slipstream caused by a
1/10 scaled metro train passing through a tunnel was studied with moving model test. We …

As more megacities emerge owing to urbanization and industrialization, the subway has
become the main public transportation mode worldwide, providing punctuality and …

The performance improvement is closely related to the energy-saving operation of urban rail
transit system and the improvement of service quality, which involves the optimization of …

At present, subways (rail transit) are undergoing rapid developments worldwide
accompanied by massive energy consumption. Train-induced unsteady airflow (TIUA) …

On-site measurements of the outdoor air supply and indoor environment in the public area
(hall and platform) in two subway stations have been conducted in cooling season in this …
