Calculations of turbulent diffusion flames are presented and compared with experimental data. In the calculation procedure, the mean continuity and momentum equations are solved by a finite-difference method, and the k-E turbulence model is used to model the Reynolds stresses. The conserved-scalar approach is used so that the local, instantaneous, thermochemical properties of the flame are uniquely related t o a single conserved scalar f ( x , 1)-the mixture fraction.

The results of calculations are compared with experimental data for three turbulent flows: an inert methane jet; a hydrogenlair diffusion flame; and a hydrogen-argonlair diffusion flame. In general there is good agreement between calculated and measured quantities, including pdf's. Numerical tests of the Monte Carlo method are also reported. These demonstrate the convergence of the method and provide an estimate of the statistical error.
