1) Surrogate Fuel and Gasoline Premixed Laminar Flame Properties
Can simple mixtures of n-heptane and iso-octane be used to emulate the combustion properties of full blend gasolines in existing and new engine cycles?
Similar model minimizations of large detailed mechanisms allow comparisons of experimental results with detailed flame speed predictions that cannot be performed with the original mechanism dimensional size.
Laminar Flame Speeds are affected by unburned gas temperature and dilution (exhaust gas re- circulation).
We are performing both experiments and model investigations.
2) Experimental Flame Speed Data
Robust kinetic models are needed to predict the combustion process in engines that use distillate fuels such as Direct Injection Diesel, HCCI or gas turbine engines.
n -Decane has some chemical characteristics similar to distillate materials.
In recent work, we have extended our prior partically reduced mechanism validation by generating new laminar flame speed data on n-decane anad validating a revised mechanism against these results as well as burner-stabilized flame, jet-stirred reactor, shock tube, atmospheric flow reactor data
3) Experimental Laminar Flame Speed Data and Model for n-Decane
Our experimental data show good agreement with the model predictions based upon the detailed kinetics developed by our group (Fischer et al., 2000)
