Default simulate a turbulence mixing flow
Posts: n/a

I am having problem with my residual. It keeps fluctuating. The physics of the burner starts with diffuser, a mixing chamber, inside of this mixing chamber there are pipe with holes to inject the gaseous fuel into the mixing chamber. The mixing chamber is having a rectangular cross section. Then the mixing goes into flame holder consist of 7 and 16 slots (I have 2 cases) and into the combustor.

Until now I haven't started my combustion simulation, because my cold flow simulation has a very bad residuals.

Is there anyone can help me to solve this thing?
