Hi

I will be very grateful if someone can provide me with the Gulder's Coefficients for laminar flame speed for Hydrogen. or tell me how I can find these coefficients for hydrogen.

many Thanks
Ali

Did you ever solve this problem or find a work around?

Hi Ali,
It maybe ca help you,

Hi. I computed the Gulder coefficients for hydrogen and other gas compounds and multicompositions in my master thesis. I developed a python script where i scripted an optimization routine based on the open-source chemical kinetics software Cantera.

I computed the Gulder coefficients for hydrogen with the GRI-Mech 3.0. Here follows the coefficients for hydrogen:


W [m/s] = 2.094
η [-] = 1.068
ξ [-] = 0.424
R**2 (W,ηξ) [-] = 0.97
Φ [-] = [0.3-2.5]
α [-] = 2.9
R**2 (α) [-] =0.99
T [-] = [250 K -961 K]
β [-] = -0.04
R**2 (β) [-] =0.78
P [-] = [0.5 atm - 10 atm]

*R**2 = Coefficient of determination
*I attached the python files inside a zip-file.

Best regards from Jonathan Johnsplass

Hello Jonathan Johnsplass,

Very nice work and thanks for sharing your python implementation.
I would like to make my own implementation, and I would like to know the articles or books that you used to get all the equations.

Thank you in advance.

Regards
