First of all, sorry for poor writing

Now, I am studying non premixed combustion simulation using the fluent.

basic boundary condition is like this photo.



and Result of pressure contour is like this



Basically, residual is not go through under 1e+2.

and Velocity contour is also too bad.

I don't know how to set the boundary condition of outlet.

in real situation, after combustion, outdoor gas is sucking into the reaction zone.

But in my case, I just use pressure outlet condition.

is there any way to express this type of simulation?

again sorry to poor writing
