Surface flame spread is a process of a moving flame in the vicinity of a pyrolyzing region on the surface of a solid or liquid that acts as a fuel source. It is distinct from flame propagation in a premixed fuel and oxygen system in that the surface spread of flame occurs as a result of the heating of the surface due to the direct or remote heating by the flame generated from the burning surface. The surface flame spread is very often critical to the destiny of fires in natural and built environments. This spread applies whether the fire is an urban conflagration or is the first growth after ignition of a roomâ€”s draperies. This chapter provides fire safety engineers with an overview of surface flame spread during the growth of a fire and the modeling of different modes of flame spread to improve understanding of their effects on the outcomes of fires.
