- Abstract
- A research program has been undertaken to study the mechanisms controlling the process of fire propagation over solid combustibles in gas flows (natural or forced) opposing the direction of propagation. Efforts are particularly concentrated in the characterization of the mechanisms of heat transfer and gas phase kinetics controlling the propagation of the fire. During the current contract period a large part of the research effort has been devoted to the study of the combined effect on the flame spread rate of the oxygen concentration and gas velocity of a forced flow opposing the direction of flame propagation. Concurrent work, although at a smaller scale was performed on horizontal flame spread in a natural convection environment. The result of these studies, particularly for forced opposed flows, represent a large step toward the final understanding of the fire propagation process.
