%X Numerical simulations of a comprehensive propane/oxygen model are used to demonstrate the ranges of behaviour  such as oscillatory cool flames and multiple stage ignitions found in a closed vessel. The model is evaluated by a  construction of the closed vessel pressure – ambient temperature (p-Ta) ignition diagram and comparing it with  experimental results. The model is then formally reduced using the techniques of sensitivity, rate of production and  principal component analyses. A reduced chemical mechanism is produced which retains the main types of dynamic  behaviour exhibited by the full model as well as their position within the p-Ta diagram. Global uncertainty analysis  methods are used to establish the main contributors to uncertainties in output predictions. Results from application  of a Monte Carlo uncertainty analysis are reported here.
