Effects of ambient pressure on the critical velocity and back-layering length in longitudinal ventilated tunnel fire

Indoor and Built Environment, 2019
Nowadays, the critical velocity and back-layering length are the key parameters in longitudinal ventilation design. However, most studies research them at standard air pressure but ambient pressure decreases at high-altitude area and the reduced ambient pressure could affect the smoke movement characteristics in a tunnel fire.
