Watt, S.D., Staggs, J., Mcintosh, A.C. and Brindley, J., 2003. Comparison Of Competitive And Non-Competitive Char Formation In Polymer Combustion. Fire Safety Science 7: 605-616. doi:10.3801/IAFSS.FSS.7-605
We consider the problem of ignition of a char-forming polymer under thermally thick conditions. In particular we explore and compare the differences in predicted ignition behaviour when models assuming competitive and non-competitive reaction schemes for char formation are used. The measure we use is the time to ignition via a critical mass flux. Finally we establish a necessary condition for the two reactions to yield different outcomes.
