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. 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 |
