Elementary Reactions in the Methanol Oxidation System. Part I: Establishment of the Mechanism and Modelling of Laminar Burning Velocities

Abstract

Abstract A set of combustion relevant rate coefficients recommended by a group of European kineticists has been tested by calculating laminar burning velocities. Virtually without any adjustments, a good match with experimental data has been achieved for H 2 /CO/air flames, H 2 /CO/air flames, and CH 4 /air flames. In order to extend this set by inclusion of the reactions forming the CH 3 OH oxidation subsystem, the current knowledge of these reactions if first reviewed. The extended set yields calculated burning velocities for CH 3 OH/air flames in good agreement with measurements recently obtained under stretch free conditions. By using a sensitivity analysis, the remaining deficiencies of the model are highlighted and it is made clear where further experimental work is particularly needed.
