Unstretched laminar flame speeds (sL0) of hydrogen-air and ammonia/hydrogen-air flames
Each file contains a table with the raw flame speed data presented in the paper
T. Zirwes, A. Kronenburg, "Assessment of Approximate Soret Diffusion
Models for Hydrogen and Ammonia Combustion", Flow, Turbulence and Combustion (2025), https://doi.org/10.1007/s10494-025-00680-5
Each table is structured as follows:
The file name contains information about the fuel composition (either pure hydrogen, "H2", or ammonia/hydrogen at a 60/40 blend by volume, "60-NH3-40-H2"), the unburnt gas temperature (either 300K or 500K), the pressure (either 1atm or 5atm) and the reaction mechanism (Stagni et al. [1] for the ammonia-hydrogen flames and Li et al. [2], Burke et al [3] or Boivin et al [4] for pure hydrogen flames).
The columns contain:
Column 1: Equivalence ratio
Column 2: sL0 from the multicomponent model without Soret diffusion (m/s)
Column 3: sL0 from the multicomponent model with Soret diffusion (m/s)
Column 4: sL0 from the mixture-averaged model with the Chaptman&Cowling Soret model (m/s)
Column 5: sL0 from the mixture-averaged model with the Bartlett Soret model (m/s)
Column 6: sL0 from the mixture-averaged model with the Hirschfelder&Warnatz Soret model activated only for H and H2 (m/s)
