The combined probability density function (PDF) /moment method which had been developed in the previous report has been evaluated in the frame of a detailed chemical kinetics. The method was implemented in the configuration of a turbulent jet diffusion flame and is evaluated through the comparison with the conventional PDF method with the detailed chemical kinetics, the flamelet model method with the flame structure on the one-step irreversible reaction and laser experiments. The present method overestimates the effect of finite reaction rate to lead to a slight deviation from the experimental values, especially in the near-field. This is caused by the ignition which is required in the PDF methods. Thus, the improvement in terms of the ignition is required. The present result is much better than the result of the conventional PDF method, reflecting the usefulness of the combined PDF/moment method.
