Fuel Autoignition Behavior

Bradley Zigler

Research output: NRELManagement


Co-development of new high-performance chemistries and high-efficiency internal combustion engines requires fast, accurate numerical simulations of critical processes to evaluate the interaction between fuel ignition behavior and advanced combustion strategies. These numerical simulations rely on accurate computational fluid dynamics (CFD) linked with fuel chemical kinetic mechanisms to model ignition and combustion performance during the engine cycle. Since fuel composition is complex, chemical kinetic mechanisms are based on surrogate compounds in representative blends. Simulation efficiency also typically requires the use of significantly reduced versions of kinetic mechanisms.
