Abstract: This paper uses a chemical kinetic modeling approach to study the influences of fuel molecular structure on Octane Sensitivity (OS) in Spark Ignition (SI) engines. Octane Sensitivity has the potential to identify fuels that can be used in next-generation high compression, turbocharged SI engines to avoid unwanted knocking conditions and extend the range of operating conditions that can be used in such engines. While the concept of octane numbers of different fuels has been familiar for many years, the variatio… Show more

“…Two strategies have been proposed which differ in the way the flamelet modification through turbulence is taken into account. The approach followed in [25,26] derives the turbulent flamelet equation from the filtered species transport. Subsequently, similarity law and scaling relations in order to estimate the filtered chemical source term and scalar dissipation rate are proposed based on a-priori DNS study in [25], while [26] suggests a source term estimation employing first-order conditional moment closure.…”
