Abstract
Downward flame spread velocity over vertical sheets of polymethylmethacrylate (PMMA) and Filter Paper were measured under the influence of externally applied radiant fluxes ranging from 0 to 2.0 W/cm(2). The flame spread rate was found to be dependent primarily on the surface temperature of the fuel prior to flame arrival. A power law correlation exists between the flame spread velocity and the difference between the vaporization temperature of the fuel and its surface temperature in the region not affected by the heat transferred from the flame.
