I'm trying to compute an axisymmetric flow field with combustion with the reactingFoam solver. I m on the 2.1.1 OF version.
I consider premixed CH4 + air inlet.
Here is my case : https://www.dropbox.com/s/mdu00b2iajf6qzx/set6.zip
But I have some trouble to ignite it..
I don't know the right length for my patch field (my chamber is 50 cm long en 10 cm ray) one can see the patch at time 0.1
I don't know either the Temperature to set (adiabatic T : 2000 K, or autoignition temperature of methane ie: 850 K ?)
In both possibility the temperature rises and then decrease instantaneously.
Should I change other parameters? in fvSolution, fvScheme, cntrolDict ?
I put a max Co number of 0.2 ...
Thank you in advance for you help,
I'm really upset with that issue since I'm working on it for weeks...
