I am simulating air flow through a furnace, but i don't see enough turbulence inside it as i imagined.
(this turbulence should be good to represent complete combustion)
I am trying to find some tutorial about these parameters (best model to my case, constants values, wall, options...) but i can't find anything helpfull. I accept tutorials and sharing contents.
This figure represents velocity and it shows where there are 2 sencodary inlet airs:
The Figure below shows only the primary inlet flow air lines (secondary flow lines are hidden)
As i said, there isn't much turbulence, most of the flow goes straight up. I want to mix primary and secondary air as much as i can.
