Modelling of high Karlovitz combustion in spark-ignition engines

Edouard Suillaud as a PhD student at IFPEN studied how to better describe the combustion in high Karlovitz1 number regimes such as those encountered in the new combustion chambers of spark-ignition engines. This description was limited by models that were not suitable for such regimes. The extension of the CFM model to “thin reaction zone regime” (TRZ) has produced promising results.
