Research Abstract

It is important to control smoke in case of a building fire. One of methods to prevent the inflow of smoke to a safety compartment is the pressurized smoke control, but this method should be carefiri to use because the supplied fresh air has a possibility to enhance a fire. The purposes in this research are to show the influence of the inflow air to fire compartment and the effect of projection to prevent ejected flame through a window. This research is constructed with two steps, one is the model experiment, and the other is a proposal of the prediction method by non-dimensional form for the trajectory of ejected fire plume through a window. The results are as following :
1) The temperature in fire compartment with supplied air becomes higher and the trajectory of ejected flame through a window is different from a usual ventilation controlled fire. The projection has a risk of spreading upstairs or neighborhoods of fire, the risk depends on the supplied air flow rate.
2) It is shown that the traditional non-dimensional form for fire plume through a window in usual ventilation controlled fire without supplied air is not able to use to predict the trajectory through a window of a fire compartment with supplied fresh air. A new non-dimensional form to predict the trajectory is proposed.
