comparison of CFD & WT
I am mainly involved in the validation work. I found that the Cn, Cm values are within 5% to the Wind Tunnel. But the drag is "OFF". The main problem is in Base Drag estimation. I have tried various TURBULENCE MODELS without success. If any one of you have successfully matched the drag coefficient, please contact me. Any suggestions about the selection of TURBULENCE MODEL to simulate wake,would be helpful. I am using 10 degree cone as the standard shape.
