Simulation of pollutant formation in turbulent combustors using an extended coherent flame model

An extension of a flame surface density model, combining flamelet concepts and homogeneous reactor combustion, is proposed to predict NO and CO formation. Results for CO in propane-air premixed flames for different equivalence ratios are compared to available experimental measurements. The agreement is good but the model is sensitive to the determination of the flamelet model parameters such as those governing the effective strain rate.
