The influence of ammonia on the laminar burning velocities of methylcyclohexane and toluene: An experimental and kinetic modeling study

Laminar burning velocities of methylcyclohexane and toluene blended with ammonia have been determined using the heat flux method at atmospheric pressure initial temperature 338 K, over equivalence ratios ranging from 0.7 to 1.3 blending fractions in binary fuel mixtures 0 90%. It was observed that addition leads a decrease laminar velocity is not proportional mole fraction. Such reduction due synergistic thermal kinetic effects. In addition, has slightly higher impact on structure The CRECK detailed model used interpret experimental measurements minor modifications methylcyclohexane, toluene, methyl-phenoxy radical chemistry allowed even improved agreement. New results compared predictions this refined mechanism. provided good capturing effect ratio fraction ranges investigated. Finally, mass fraction-based mixing rule shown be predictive for blends NH3 methane several hydrocarbons typically formulate surrogates practical fuels.
