Abstract:

The increasing number of species and reactions in the combustion mechanisms has caused inconvenience to the engineering application of turbulent combustion simulation. The minimized reaction network method was adopted to develop combustion mechanisms for typical C2 fuels such as ethylene, ethane and ethanol under specific chemical resolution. Each C2 single mechanism features a compact reaction network with reversible reaction. Moreover, the direction of all reactions was unified in form. For kinetic parameters, the form of classical Arrhenius equation with two parameters(AEa) was adopted. This choice ensures physical significance while facilitating parameter optimization. The mechanism reduction process was avoided in the development of the C2 mechanisms, while the number of species and reactions were significantly decreased. The simulation results indicate that the C2 combustion mechanisms developed in this work exhibit high reliability while maintaining small scales, which may bring convenience to the practical engineering application of the mechanisms by reducing computational costs.
