isaac1326 New Member Isaac Join Date: Feb 2013 Posts: 27 Rep Power: 13	Hi, Im doing a CFD analysis(STAR-CCM+) on a NACA 0012 wing, with a AR of 5.0 at a Re number of 80000. I am validating it with an experimental data. Im still unsure which model I have to be using , whether to go with laminar or use turbulent BL. When I have used , laminar model, the lift coefficients matched, but the drag coefficients are far way off. Experimental @ 5 degrees Cl - 0.4, cd -0.12. My analysis Cl -0.38, cd -0.06. Any help in helping me solve this, is deeply appreciated
