Abstract
- Numerical study is conducted to grasp preferential diffusion effects on flame characteristics in syn-gas diffusion flames diluted with . The models of Sun et al. and David et al., which have been well known to be best-fitted for synthetic mixture flames. are evaluated for synthetic mixture flames diluted with . Comparison of flame structures with mixture-averaged species diffusion and suppression of the diffusivities of and H was made. The behaviors of maximum flame temperatures with those species diffusion models are not explained by scalar dissipation rate but by the nature of chemical kinetics. Importantly-contributing reaction steps to heat release rate are also compared for the three species diffusion models in flames with and without dilution.
