Full-Scale Ezperiments for Investigation of Effects of Ventilation Systems on Tunnel Fires
(0) To investigate the first three ventilation modes: natural ventilation, fully-transverse ventilation and semi-transverse exhaust, a full-scale experiment was conducted with two different fire intensities of 0.75MW and 1.5MW as stipulated in AS4391 (1999) and the spatial temperature was recorded. The data was analyzed and compared case by case. The experimental results have shown that the ventilation system plays an important role on both fire development and heat removal. Interestingly, semi-transverse exhaust ventilation system gave the lowest temperature profile along the tunnel. These experimental studies also provided important and useful data for further studies of tunnel fires using Computational Fluid Dynamics (CFD) techniques.
