DATA: hydrogen and ammonia flame speeds from different Soret diffusion models

<h3>Unstretched laminar flame speeds (sL0) of hydrogen-air and ammonia/hydrogen-air flames</h3>

<p>
Each file contains a table with the raw flame speed data presented in the paper
<p>
<b>T. Zirwes, A. Kronenburg</b>, "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
</p>
</p>

<p>Each table is structured as follows:
</p>
<p>
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).
</p>
<p>The columns contain:
<ul>
<li>Column 1: Equivalence ratio</li>
<li>Column 2: sL0 from the multicomponent model without Soret diffusion (m/s)</li>
<li>Column 3: sL0 from the multicomponent model with Soret diffusion (m/s)</li>
<li>Column 4: sL0 from the mixture-averaged model with the Chaptman&Cowling Soret model (m/s)</li>
<li>Column 5: sL0 from the mixture-averaged model with the Bartlett Soret model (m/s)</li>
<li>Column 6: sL0 from the mixture-averaged model with the Hirschfelder&Warnatz Soret model activated only for H and H2 (m/s)</li>
</ul>
