Étude cinétique de la combustion en flamme prémélangée de molécules modèles présentes dans les gazoles

Abstract : The HCCI engine could be an interesting alternative to conventional combustion processes. However, the control of the combustion remains difficult in this engine because, unlike the gasoline and diesel engine, it is directly related to the chemical oxidation of fuel. The development of accurate detailed kinetic models of the oxidation of fuel is therefore essential to control this mode of combustion. The aim of this PhD was to develop and experimentally validate high temperature kinetic oxidation models for 3 molecules representative of diesel fuel by using a flat flame burner experimental device. This study presents new experimental results obtained in a lean laminar premixed methane flame seeded respectively with n butylbenzene, n propylcyclohexane and indane. A kinetic oxidation model was developed and validated at high temperature for n-butylbenzene and another one was validated in flame for n propylcyclohexane. Overall, the models correctly simulated the profiles of most products measured in the flames. Moreover, a qualitative kinetic model for the oxidation of indane has been proposed
