Abstract
To satisfy the needs of large-scale hydrogen combustion and explosion simulation, a method is presented to establish single-step chemistry model and transport model for fuel-air mixture. If the reaction formula for hydrogen-air mixture is H2+0.5O2→H2O, the reaction rate model is ω̇ = 1.13×1015[H2][O2]exp(−46.37T 0/T) mol (cm3 s)−1, and the transport coefficient model is µ=K/C P=ρD=7.0×10−5 T 0.7 g (cm s)−1. By using current models and the reference model to simulate steady Zeldovich-von Neumann-Doering (ZND) wave and free-propagating laminar flame, it is found that the results are well agreeable. Additionally, deflagration-to-detonation transition in an obstructed channel was also simulated. The numerical results are also well consistent with the experimental results. These provide a reasonable proof for current method and new models.
