Hello,

Can anyone at least suggest to me someway of setting up the following problem in Fluent? I have a gas combustor which uses a swirler to rotate the incoming flow about the centerline axis of the combuster (lets say the combustor has a can-shape). I would like to model this as 2D axisymmetric with swirl. I set up inflow and outflow boundary conditions into and out of the can combustor, but what boundary conditions can I use to represent the swirler, which is basically rectangular shaped, located 1/3 downstream of the inflow and must change the path of the flow? Any help would greatly be appreciated. Tom

i think you must have a 3d model for swirl and i think whith 2d model swirl modeling is impossible. could you send me your 2d model dwg. then may be i can help you. bye
