EXPERIMENTAL AND NUMERICAL STUDY OF F-T/BIODIESEL/BIOETHANOL SURROGATE FUEL OXIDATION IN JET-STIRRED REACTOR
Blends of Fischer-Tropsch (F-T) fuels, biodiesel, and ethanol seem to be a promising fuel for compression ignition (CI) engine applications. An advanced control of current diesel engines requires a detailed comprehension of the fuel chemistry in terms of auto-ignition and pollutant formation. However, neither experimental data, nor convenient combustion models are available for such an alternative fuel. Therefore, the kinetics of oxidation of F-T, F-T/biodiesel, and F-T/biodiesel/bioethanol surrogate fuel (n-decane, iso-octane, methyl octanoate, and ethanol) were studied experimentally in a jet-stirred reactor (JSR) at 10 atm and constant residence time of 1 s, over the temperature range of 560-1160 K, and for several equivalence ratios (0.5-2.0). The oxidation of these fuels was modeled using a detailed chemical kinetic reaction mechanism consisting of 9919 reactions and 2202 species. The proposed kinetic reaction mechanism yields a good representation of the kinetics of oxidation of the tested biofuel blends.
