duct- Fletcher's technical note
I'm doing simulation for a duct with AR=1 and comparing the results to the NASA technical Note by Fletcher (Experimental Investigation of Lift, Drag, and Pitching Moment of Five Annular Airfoil.
Right now, this is the detail of my simulation: 1) Duct based on Clark Y 2) M=0.13, V=44.2 m/s 3) Grid: 1 million 4) boundary: 20c (chord)-> pressure far-field, duct->wall, no slip 5) solver: coupled-implicit 6) viscous: S-A 7) alpha: 0 to 90 with 10deg interval 8) energy equation included because I use ideal gas (Fluent do it automatically)
the problem now is that the results deviate quite far from the experimental results. I have tried other BC, viscous, etc yet the results are still bad.
Can somebody help me?
Thank you in advance
