“…According to some relative Refs. [16,17], the boundary condition for rock should be set as a ''wall" with an effect thickness and distal fixed temperature, and the heat flux from the rock ranges between 0.83 W/m 2 and 7.74 W/m 2 (at cooling working conditions) according to some comparative simulation works of underground hydropower stations.…”

Air quality in a subway tunnel has been crucial in most of the subway environments where IAQ could be affected by many factors such as the number of passengers, the amount and types of ventilation, train operation factors and other facilities. A modeling approach has been introduced to manage the general IAQ in a subway station. Field surveys and CO 2 measurements were initially conducted to analyze and understand the relationship between indoor and outdoor air quality while considering internal pollution sources, such as passengers and subway trains, etc. The measurement data were then employed for the model development with other statistical information. For the model development, the algorithm of simple continuity was set up and applied to model the subway IAQ concerned, while considering the major air transport through staircases and tunnels. Monitored CO 2 concentration on the concourse and platform were correlated with modeling results where the correlation values for the concourse and platform were R 2 =0.96 and R 2 =0.75, respectively. It implies that the box modeling approach introduced in this study would be beneficial to predict and control the indoor air quality in subway environments.

“…The simulations were performed for trains with different initial speeds in a uniform stop process, different temperature fields, and different speeds in the subway tunnel [18]. To simulate a transfer station, Pflitsch et al measured the air flow speed and the temperature on a British transfer station and used a series of rules for air flow in the station [19]. Ke et al studied the distribution of a trolley bottom exhaust tube for different speeds, different shaft broken areas, and different lengths for velocity and pressure in the tunnel.…”

In recent years the piston effect in subways has become a topic of interest for researchers and engineers. Many publications have appeared on this topic, but reliable information is scattered and poorly organized. This review paper covers the latest publications on the piston effect in subways. We compile information about the mechanism of the piston effect, evaluate its influence, and describe how it can be effectively utilized.
