Hello. I am simulating with fluent 2D- transient, axisymmetric swirl and UDF- the partially premixed combustion of biogas (40% ch4+60%co2) in a spark ignition engine for different values of equivalence ratio. My problem is that the temperature is always raising for all cases, which is not normal! Please help me
The chemical reaction is:
CH4+1.5CO2+3/ϕ (O2+3.76N2 )→2.5CO2+2H2 O+(3/ϕ-2)O2+11.28/ϕ N2
