VICENTE, W.; SALINAS, M.; RODRIGUEZ, A.  y  JIMENEZ, R.. Turbulence Model Evaluation in Premixed Combustion Flows. Inf. tecnol. [online]. 2004, vol.15, n.2, pp. 29-34. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642004000200006.

The influence of the turbulence model on CO and NO formation in a turbulent methane flame, is studied. A stochastic model is used in the numerical simulation. This model is based on the combination of the Finite Volumes and the Monte Carlo methods for the solution of the joint scalar Probability Density Function. Rate reactions are represented by a reduced chemical kinetics model that is derived form a complete GRI mechanism. A lean, premixed and bluff-body-stabilized flame is studied from the stochastic model. Different turbulence models are tested and compared. Results show that species such as CO and OH are strongly affected by the turbulence model; nevertheless, others such as NO are not affected
