Tsotsis, Auteur Année de publication : 2012 Article en page(s) : pp. 9719-9732 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Fuel Modeling Flame Résumé : The nitrogen oxide formation characteristics of a class of model biodiesel fuels, namely fatty acid esters, were studied in both premixed and nonpremixed flames. The experiments were conducted in the opposed-jet configuration at atmospheric pressure and for various reactant concentrations. The measurements were performed using a quartz-probe sampling method. Flames of the model biodiesel fuels were determined to form significantly less nitrogen oxides when compared to the corresponding n-alkanes. Additional experimental studies were carried out in order to assess the effects of carbon number, type of ester group (methyl or ethyl), and the extent of saturation on the nitrogen oxide concentrations in flames of these model biodiesel fuels. Three recently developed chemical kinetic models were utilized in order to model the experiments and to investigate the relative contributions of the four different nitrogen oxide pathways to the nitrogen oxide formation in these flames as well as to provide insight into the differences that were determined experimentally in flames of the various model biodiesel fuels.
