Dear everyone,

If anyone have a reduced or skeletal mechanism of methane, please share your .inp and .dat files (chemkin version of openfoam version). Thank you very much.

I am currently running a case about methane combustion using reduced version of GRI-MECH 1.2. 19 species (+ N2, AR) 84 reactions. If the inlet temperature of air was set 300K (experimental condition), the flame will gradually goes to extinction. If the temperature was set 400K or above, things goes right. I have tried using hot (like 1800K) initial temperature condition in the reaction domain, setting many ignition points, increase the resident time of the igition, etc.

Considering changing other reaction mechanisms of methane may solve the problem, I have searched a couple of days but find all of them have problems, for example.

It seems A 19-species reduced mechanism, and a 30-species skeletal mechanism ( http://www.engr.uconn.edu/~tlu/mechs/mechs.htm ) do not give the values of E, A, n.

The 4 step reaction meachnism mentioned here ( http://www.cfd-online.com/Forums/ope...mechanism.html ) do not give a answer.

Thanks again.

Tom
