Opposed-flow flame spread in a narrow channel: Prediction of flame spread velocity

This paper presents results of experimental and numerical investigations of flame spread along a thin solid in an opposed oxygen flow in a narrow channel. Experiments are conducted at various oxygen flow speeds and gas-phase heights. For a low gas-phase height or a low oxygen flow speed, a large portion of solid is left unburned, and the burned region forms a finger-like pattern. It is noted that both the flame spread velocity and the fraction...
