Rana.P is on a distinguished road
Hi guys,
i'm using fluent to study combustion in a micro burner.the mixture i use is methane-air with a step chemical mechanism.the problem is that the residuals of ch4 & energy remain costant. so the solution didn't converge.the other problem is that the temperature is higher than flame adiabatic temperature in about 3000 cells.

the geometry is a 5mm*50mm plane.

Does anyone has suggestions on my problem?

many thanks!
