Downward flame front spread in thin solid fuels: theory and experiments

Full Text
Flame spread over solid samples has been studied from many points of view, as it is key for fire safety, yet it is a complex phenomenon that involves processes occurring in both the solid and the gas phases. This Ph.D. thesis studies the flame spread over thin solid samples in processes more complex than the classical cases where a flame spreads horizontally or downward over a vertical solid sample. In particular, this thesis deals with three different situations: the effects of the sides to the vertically downward flame spread over a thin solid; the effects of having various parallel samples burning simultaneously, and flame spread over horizontal and downward inclined samples. For all these situations a complete experimental study is made and a model that explains the obtained results is developed ​
