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 |
