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. date: 2005-04-03 date_type: published publisher: European Combustion Meeting (ECM) official_url: https://www.ntnu.edu/fesci/previous-meetings oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 2116984 lyricists_name: Porter, Richard lyricists_id: RTJPO82 actors_name: Porter, Richard actors_id: RTJPO82 actors_role: owner full_text_status: public pres_type: paper publication: Proceedings of the European Combustion Meeting place_of_pub: Louvain la Neuve, Belgium event_title: The 2nd European Combustion Meeting event_location: Lovain-La-Neuve event_dates: 3 Apr 2005 - 6 Apr 2005 book_title: Proceedings of the European Combustion Meeting 2005 citation: Battin-Leclerc, Frederique; Buda, Frederic; Fairweather, Michael; Glaude, Pierre-Alexandre; Griffiths, John; Hughes, Kevin; Porter, Richard; Battin-Leclerc, Frederique; Buda, Frederic; Fairweather, Michael; Glaude, Pierre-Alexandre; Griffiths, John; Hughes, Kevin; Porter, Richard; Tomlin, Alison; - view fewer <#> (2005) The Effect of Formal Mechanism Reduction on Simulated Propane Autoignition and a Quantitative Assessment of the Impact of Uncertainties in Parameter Values.
