Journal ArticleDOI
Upward turbulent fire spread and burning of fuel surface
TL;DR: In this article, the upward spread and subsequent steady turbulent burning of a thermally thick vertical fuel surface is examined theoretically and experimentally, showing that the rate of upward spread increases exponentially with time.
Journal ArticleDOI
Effect of Moisture on Ignition Time of Cellulosic Materials
TL;DR: In this paper, the effect of equilibrium moisture content (ranging from 4 to 12.5% moisture, corresponding to 20 to 90% relative humidity) on piloted ignition times of single wall and tri-wall corrugated paperboard samples has been measured over a range of external radiant heat flux (10 to 60 kW/m 2 ) in the Fire Propagation Apparatus (ASTM E-2058).
Journal ArticleDOI
Flame Heat Transfer Between Parallel Panels
J.L. De Ris,L. Orloff +1 more
TL;DR: In this paper, the authors measured flame heights and flame heat flux distributions for a wide range of fuels burning between two parallel panels, and integrated the heat flux distribution to obtain the net total heat transfer to the panels above an arbitrarily specified panel heat loss rate.
Journal ArticleDOI
The Of Role Of Smoke-point In Material Flammability Testing
J.L. De Ris,X.F. Cheng +1 more
TL;DR: In this paper, a horizontal fuel sample is continuously fed into a downward pointing C02 laser beam which pyrolyzes a small area of the sample, and the heat release rate (or flame height) of the steady laminar flame produced by the pyrolys gases is controlled by the laser beam power and for the sample feed rate.
Journal ArticleDOI
Similarity Of Turbulent Wall Fires
TL;DR: In this paper, the authors established a similarity relationship controlling the buoyant turbulent boundary layer combustion of wall fires, which is suitable for development of analytical and CFD models of turbulent wall fires.
