Capability Title Reduced kinetic mechanisms for new fuels and blended with gasoline or diesel fuels
Laboratory Lawrence Livermore National Laboratory (LLNL)
Capability experts Goutham Kukkadapu (LLNL), Simon LaPointe (LLNL), Scott Wagnon (LLNL), Russell Whitesides (LLNL)
Description Reduced mechanisms for fuel components, fuel blends, and surrogate mixtures (to represent real fuels) will be developed based on detailed chemical kinetic models and using mechanism reduction techniques of DRG EPSA, hybrid method, and expert knowledge. The reduced models will be developed to target key qualities (ignition phasing, flame speed, heat release rate, emissions) over a wide range of temperature, pressure, equivalence ratio and EGR.
Unique aspects Reduced chemical kinetic models are used in multidimensional engine codes to simulate the effect of fuel chemistry on ignition phasing, heat release rates, flame propagation, engine knock, miss-fire, flame quenching, and emissions.
Availability Mechanism reduction capabilities are limited by availability of staff.
