Abstract: This study introduces a new multi-featured equilibrium combustion model for fuels, fuel blends and surrogates which estimates mole fractions, adiabatic flame temperature and thermodynamic properties of the equilibrium combustion products. The model enables simultaneous consideration of unlimited number of CαHβOγNδ type fuels of different ratios and also enables any CαHβOγNδ type fuel additive, Argon, H2O, CO, CO2, N2, and O2 to be considered among the reactants. Equilibrium mole fractions and adiabatic flame temperature are not only necessary for estimating thermodynamic properties of exhaust gases but also provide key data to obtain the non-equilibrium concentrations. As for thermodynamic properties, precise calculation is necessary for accurate performance estimations of internal combustion engines. Meeting these fundamental needs and providing combustion analysis of numerous fuel blends of various mixing ratios, this new model can be a recourse tool for researchers working on fuels, surrogates, emissions and internal combustion engine modelling. Simulations of any combustion process including existence of exhaust gas recirculation, supplementary firing, steam injection, argon dilution, water injection, fuel emulsification and reheat process in gas turbines can easily be conducted by integrating this validated model into thermodynamic cycle models.
