Hello, I have to simulate the non premixed combustion in a combustion chamber camera combustione.jpg,
but i didn't understand very well how to do it .
As you can see in the figure I have 2 inlets: fresh air and fuel, they have different pressure, temperatures and obviusly density and composition.
In fluent if I turn on the model Species-Non Premixed combustion and I do all the steps shown in the figures (included the PDF Table),IM1.PNGIM2.PNGIM3.PNG
in the materials disapperars the material air, so in the cell zone condition I can't set for the domain named "air" (see the figure) that the fluid inside is fresh air and not mixture,IM5.PNG
I have the same problem with the domain fuel. How can I fix this problem?? I hope I was clear, If I was not please ask me because I absolutely have to fix this problems very soon.

Bye Bye
