Flame Generated Manifold (FGM) model
I am doing a combustion simulation with FGM model and the following characteristics:
1- Non-premixed combustion with heat loss
2-Fuel CH4 at 446K
3 Oxidizer preheated at 843K.
When selecting combustion model I choose the options of the attached images.
In Boundary conditions I define in fuel Mixture Fraction =1.
In Materials I modify absorption coefficient
I patch progress variable to 1, and I obtain the temperature contour attached. Something seems to be not working at flame shape is to small. Any suggestion?
Thank you in advance!
