摘要
The theoretical and design work of the tunnel ventilation system is described. The subjects discussed cover ventilation and piston effect; instantaneous velocity distribution in tunnels and draft relief cross passages; pressure profile in main tunnel near to a train; pressure pulses on train and instantaneous aerodynamic power; idealized pressure distribution in tunnel systems; and pressure at fan under operating conditions.
