Abstract
Turbulent nonpremixed H2/Air flames are simulated using direct numerical simulations coupled with detailed chemical schemes, complex transport models and accurate thermodynamic parameters. Typical results and post-processing procedures based on these results are presented in this paper. The choice and definition of a mixture fraction appropriate to describe turbulent mixing is discussed. The influence of differential diffusion is investigated comparing the present results with similar computations using a unity Lewis number hypothesis. Differences due to differential diffusion concerning global flame structure as well as conditionally-averaged quantities are emphasized.
