A modeling study has been performed for several kinds of dual-component fuel spray. A source code of SUPERTRAPP developed by NIST has been incorporated into KIVA3V to predict physical fuel properties and vapor-liquid equilibrium. A multistep kinetics Shell ignition model and a global single-step mechanism have been employed to account for low temperature and high temperature oxidation reactions, respectively. The calculated results were in good agreement with experimental ones obtained in a constant volume vessel for wide variety of fuel compositions. Using this model, additional investigation was performed to examine a feasibility of combustion control strategy by means of batch-distillation vaporization process of dual-component fuel.
