Laminar Flame Speeds of Methanol and Ethanol at High Pressure and Temperature Conditions: An Experimental and Modeling Approach
Résumé
Laminar flame speed is one of the fundamental properties characterizing a fuel and is used for the validation of chemical kinetic mechanisms. However, most of the databases available for such a key parameter are still limited in thermodynamic conditions. In the present study, laminar flame speeds were determined experimentally for different methanol/O2 and ethanol/O2 diluted mixtures under a wide range of conditions. The aim of this study is to provide new laminar flame speed data for methanol and ethanol, covering high pressures and temperatures previously unexplored. These data of such small alcohols contribute to the base mechanism of kinetic models as validation targets. Therefore, a kinetic mechanism was also developed in this work and was tested on the present experimental results as well as on other literature data to serve as a robust core mechanism in the future
