- Abstract
- The purpose of this study is to predict theoreticaslly whether or not an upholstered furniture item will be ignited to smoldering when a lit cigarette is dropped on it. To do this, the heating of the substrate when subjected to a moving heat source must be accurately modeled, and a criterion established for its ignition. In order to examine how changing one or more properties of the cigarette will influence its ignition propensity, it is also necessary to understand the behavior of a smoldering cigarette. This includes knowing how its external heat flux and burning velocity depend on its various geometrical, physical, and/or chemical properties, and how these processes are modified when the cigarette lies on the substrate.
