Abstract
A model tunnel (1:30 compared to a standard tunnel section) with a helium-air smoke mixture was used to study the vehicular blockage effect on longitudinal ventilation smoke control. The experimental results showed excellent agreement with full-scale data and confirmed that the critical velocity decreases in proportion with the blockage ratio. Nevertheless, it was found that the relative position of the fire source and the relative size of the vehicular blockage can have an opposite effect, as the vehicular blockage influenced the critical and confinement velocity. The method demonstrated the ability to provide valuable information on the effect of vehicular blockage on tunnel fire dynamics.
