Abstract
A modeling method for spray combustion with a real fuel is proposed and validated. A total of 22 species are defined as palette species for the modeling of market fuels based on two-dimensional gas chromatography and hydrogen nuclear magnetic resonance spectroscopy. A surrogate fuel model is formulated to best reproduce the distillation curve and the reactivity of the real fuel. Large-eddy simulations are performed for spray combustion with the surrogate fuel model. The results showed that a local hot spot develops into ignition with the equivalence ratios raging from one to six, indicating that the modeling of reaction and mixing at fuel rich side is significantly important.
