i am simulating a 3D model of a burner. I created a 45 degree view geometry of the burner with periodic boundary conditions. i m using RSM model since i heard it is gud for a swirl no of 0.7. While solving for unsteady conditions, the results dont seem to match the experimental streamlines. I am not getting the axial recirculation at all...!!!wat do i do???is it because of the 45 degree model??? shud i model the full 360 deg view??? or shud i change the turbulence model to LES???
