Abstract

Detailed process of upward fire spread along a mild steel cylinder in high pressure oxygen has been studied by using high speed photography. Fire spread experiments were conducted in a cylindrical, high pressure oxygen chamber of a capacity of about 2.5x107 mm3. The movement of a molten mass attached to the bottom end of a burning steel cylinder and that of a molten mass droplet detached from the bottom end were recorded by a 16 mm or 35 mm high speed cinecamera and analyzed. By analyzing the oscillatory behavior of the molten mass droplet, its main component was inferred to be iron oxide. The local spread rate fluctuation was observed during a period of the overall cyclic behavior. Based on the location of the observed high luminosity region and surface flow of the molten mass, convection was inferred to be a dominant mode of heat transfer at the molten-solid boundary and the fluctuation of the local spread rate was supposed to be attributable to the nonuniformity of the convective heat transfer at the molten-solid boundary.
