Transition from Smoldering to Flaming Fire in Short Cotton Samples with Asymmetrical Boundary Conditions

Report Date: December 2014

Why do smoldering fires sometimes remain smoldering and other times transition to flaming fires? This question and related hazard are applicable both to structural fires and wildfires. Earlier studies have found that two-thirds of smoldering fires from cigarettes on furniture and half of smoldering fires in leaves transitioned to flaming fires.This paper tires to quantify and explain this seemingly random phenomenon using a set of experiments with cotton batting and a hotplate as an ignition source. This information can be used to get a better understanding of fire growth.
