Adding Hydrogen
Hi all,
I am beginning to use FireFoam Solver for modelling a Jet in Hot Coflow fuelled with a mixture which is made up of methane and hydrogen. I have successfully run my first methane -air case :confused:. I am thinking to add hydrogen since I have hot a lot of papers which includ a lot of experimental results for methane/hydrogen mixture. What can I do to add hydrogen in the mixture (I have never written in C++ :eek:)? Which files should I set properly to do that? I think of modelling this flame by two different combustion models (EDC and Mixture Fraction). Thank you in advance for your time. Cristiano |
Hello everybody
Sorry Cristiano, I am also a beginner with firefoam and I cannot help you in this question, at least for now. I am still learning to use openFoam, and especially fireFoam. I reply because I am interested in what you did with the methane-air flame. Did you succeed in running a methane-air diffusion jet flame, such as Sandia flame? Because that's what I am trying to do, but without success for now. I tried a lot of different conditions and solvers but never succeed. What are the boundary conditions you choose for the velocity, pressure, and for b, ft and fu ? (if I am right, b is the normalized fuel mass fraction, ft is the total and fu is the unburnt fuel mass fraction in the veryInhomogeneousMixture thermophysical model) ? Can you tell us more about this succeeded methane-air case? thanks a lot, Maxime |
