- Abstract
- Downward flame spread along a white index card has been investigated in some detail. Visual observations as well as temperature measurements confirm the release of the pyrolysis gases underneath the flame rather than ahead of it. The extension of the flame beyond the pyrolysis zone due to gaseous diffusion preheats the surface to the pyrolysis temperature by gas phase heat conduction thus causing the flame to move. Because of symmetry the downward flame spread on each side of the card can be treated as flame propagation along a single surface. A flame spread burner was constructed to simulate this surface. An equaiton was developed to predict the flame spread rate.
