The local reaction rate and the diffusion rate may be useful values for the study of turbulent diffusion flames. but they cannot be directly measured. In this study, an attempt was made to obtain them by numerical calculation using measured values for a hydrogen jet diffusion flame. The following results were obtained. (1) The correlation between fluctuating velocities u″v″^^^〜that were obtained with the developed method was compared with the measured value. As a result, the method was revealed to be reliable. (2) The molecular diffusion coefficient of hydrogen becomes large and not negligible compared with the turbulence diffusion coefficient, in a high-temperature reaction region of comparatively weak turbulence. (3) It was suggested that the method developed in this study has the capability of giving reasonable values for local reaction rates in a hydrogen jet diffusion flame.
