Oka, Y., Kurioka, H., Satoh, H., Miyake, Atsumi and Ogawa, Terushige, 2004. Effect Of Fire Source Shape And Its Size In A Tunnel Fire. AOFST 6
Experiments were carried out to investigate the effects of fire source shapes and those sizes to the fire property using the model tunnel which has a rectangular cross section and its aspect ratio is 1:2. Square and rectangular burners were used as model fire sources. Heat release rate was changed from 4.5 to 36 kW in proportional to the fire size and longitudinal ventilation velocity also varied in the range of 0 to 0.8 m/s. Flame tilt angle, maximum temperature rise of smoke layer near the ceiling and its position were adopted as the variables which characterise the fire phenomena in the near field of fire source in the presence of longitudinal ventilation. New empirical formulae considering the effects of the fire source shapes and those sizes for these variables were developed.
