Combustion and Flame, 2003
Flame-spread phenomena over thin solids are investigated for purely forced-opposing and concurrent flows. A two-dimensional, opposed-flow, flame-spread model, with flame radiation, has been formulated and solved numerically. In the first part of the paper, flammability limits and spread rates in opposed flow are presented, using oxygen percentage, free-

Symposium (International) on Combustion, 1996
Limitations of the assumptions in the classic de Ris formula [1] for opposed-flow flame spread rate over thick fuels in the thermal regime are explored through numerical experiments in which the assumptions used in the original theory are eliminated one by one from the mathematical model.

Proceedings of the Combustion Institute, 2002
The influence of channel height on flame spread in a circular duct of the solid fuel in an opposed-flow configuration was examined. Polymethylmethacrylate cylinders with a circular duct (diameter of 1, 2, or 3 mm) were used as fuel specimens, and both flame-spreading and stabilized combustion were observed.

Exact Solution for the Rate of Creeping Flame Spread over Thermally Thin Materials
Combustion Science and Technology, 1986Abstract In this work we present the exact solution for the rate of creeping flame spread over thermally thin materials based on de Ris' (1969) formulation of the problem. The publication of the present work was prompted by a recent paper by Wichman and Williams (1984). These authors noted that de Ris (1969) obtained theoretical values for flame spread
