Modelling CH4/air turbulent non-premixed combustion with the Monte Carlo composition PDF method

Turbulence-chemistry interaction in turbulent nonpremixed CH4/Air combustion is accounted for solving a transport equation for the composition probability density function (PDF) via a 'node based' hybrid finite volume/Monte Carlo technique, The thermochemical model is based on a two-step global mechanism able to account for CO oxidation kinetics. Turbulent transport is accounted for via a standard k - epsilon model. Validation is performed comparing the numerical results with the experiments for a CH4/Air confined flame.
