Abstract
In order to acquire fundamental data on the characteristics of open fires in inclined galleries and the change in ventilation characteristics caused by the fire, a series of experiments have been carried out, using two types of model gallery. The results of the investigation are summarized as follows; (1) The effect of the inclination of the gallery on the spread rate of the timber fire was quantitatively clarified in both cases of upward and downward spread of the fire. (2) Buoyancy effects created by the fire in a inclined gallery contributes to reducing the pressure loss of ventilation in case of ascensional ventilation and to increasing it in case of descensional ventilation. (3) A method is proposed for estimating the fire spread rate and the fire zone length, the variation of ventilation cased by fire and the effect of the inclination of the gallery being taken into consideration.
