Sutherland, Arrhenius constant for hydrogen combustion

Arpit Singh · April 18, 2023, 02:24

Hello guys, can anyone help me find the Sutherland constants (As, Ts) for species H2, O2, H2O, and Arrhenius constants (A, Beta, Ta (requires in OpenFOAM)) for the following reaction:
2H2+O2=2H2O;
Currently, I am stuck here not able to find these values anywhere.

Real reactions of H2 and O2 are multi-step reactions and have intermediate species. For that I recommend Burke or something more recent.

Single step reactions like the one you have shown are global reactions, which are models of the real deal. There are infinitely many variants of these depending on what the model is tuned for. But one such model that I just randomly googled is here.
