The ignition in FireFoam
 

Hello Foamers,
I am doing the test case with Firefoam (the case CoFlowFlame2D) but I can not understand how do we burn CH4 in air. Could someone tell me, please?
Thank you very much,
NTD

Hi ntd,

I don't know if that's what you want (you post is a bit vague...), but:
How CH4 burns in the air =>
CH4 + 2 O2 + N2 = CO2 + 2 H2O+ N2

Thanks for your reply, Sam
I understand that there is this reaction but how did they do the ignition to burn CH4?

NTD

maybe?
 

Hi Nation
 

Thanks for your reply Nation,
Yes, that is the problem. I found in version 1.6 the file fireFoamPropertie likes below
