Abstract
This U.S. Bureau of Mines paper presents a quasi-steady-state mathematical model of fire growth along a ventilated horizontal fuel surface. The model couples an equilibrium state combustion zone confined by the roof above the pyrolyzing surface with a tilted flame front that preheats the fuel surface ahead of the combustion zone in a transient mode and is used to predict the growth of the pyrolyzing surface. Radiative and convection heat transfer to the fuel surface ahead of the flame front are included. The total flame emissivity includes gas emissivity for the co2 and h2o in the product-of-combustion gas and the particulate emissivity. Material burn-through is included. Predicted transient fire growth along a styrene butadiene rubber material is analyzed for the effect of ventilation and entrainment and is in reasonable agreement with measurements.
