Good morning.
I am operating a simulation of a combustion chamber that uses a syngas consisting of a gas mixture (ch4,co,n2,co2,h2) present in different proportions.
combustion is not pre-mixed (gas and air enter from two different inputs).
I operated a simulation with only propane to test the model and had no problem in the simulation.
switching to syngas instead the simulation does not provide good results. I think the problem lies in the introduction of boundary conditions and in particular in fuel input (syngas) when I go to define the composition of the gas mixture. in the post processing I have verified that the mass fractions are not assimilated by the program correctly and gives me pressure problems, besides the fact that the field of temperature, both for distribution and as range of values, is absolutely far from the real case, presenting instead an unrealistic trend.
If anyone had any advice on this, I'd be very grateful.
